My stepdaughter’s mom, stepdad, and baby sister just moved out after living with my husband and me for three months. Yep, you read that right. My husband’s ex-wife and I lived under the same roof for a quarter of a year.

I had to learn a few lessons the hard way, and though you probably won’t find yourself under the same roof with your husband’s ex, they’re still important lessons for any stepmom in a co-parenting relationship.

What I Learned From Being Roommates with my Stepdaughter’s Mom

The Importance of Boundaries

The concept of boundaries felt foreign to me when Amanda moved in. There are really obvious boundaries when you live in separate homes; you know that if you walk out of your bedroom and into the kitchen and see his ex making a sandwich, that crosses a boundary. But when you live under the same roof, those same rules don’t apply.

When they first moved in, Amanda went as quickly as she could to unpack their belongings to ensure we wouldn’t be living with a mess. It was super thoughtful of her, but for me, it was really overwhelming. My husband and I had actually just purchased this new home and moved in ourselves less than a week before they did. She was quick to fill up wall space that I hadn’t had a chance to fill yet, and I learned the hard way that decorating this new space was a boundary of mine.

In every stepmom/mom relationship, there need to be boundaries. Those are going to vary for each relationship, but they need to be identified.

Examples of common boundaries are not allowing another woman into your home, or texting about anything pertinent to your stepchildren during agreed-upon hours. Boundaries aren’t one size fit all, so set the boundaries that make sense for you.

Stepmom is #2

Another lesson I learned the hard way is that stepmom is number 2. It sounds obvious, right? Yet somehow I hadn’t learned it or accepted it or just didn’t want to see what was right in front of my eyes.

I spend so much time with my stepdaughter during the week; I pick her up from school three days a week and it’s just the two of us until Dad gets home from work a couple of hours later. We share inside jokes, have daily routines, and genuinely enjoy each other’s company. She’s my little sidekick.

But as soon as Mom moved in, our relationship got moved to the back burner. Mom stays at home during the day, so she was always there when we returned from school. My stepdaughter forgot our routines and instead went upstairs to see Mommy and Sister after school. She didn’t see the custody schedule and instead just chose to spend time with whomever she wanted – the way things should be for a 7 year old!

But for this grown up, the feelings of inferiority and jealousy were hard to deny. I had to come to grips with the fact that no matter how close my little one and I are, I’ll never be as special to her as her mom is.

I know that we are buddies and she’s my sidekick and we can continue to be buddies without my being her first choice. At its core, stepparenting is about choosing someone else even when you know you’re not first choice. I know this, and yet it still stings a little.

Though it was a tough lesson to learn, it was critical that I face the facts.

No Matter How Good You Are, Being the 2nd Wife Sucks

I thought I had fully accepted that I was my husband’s second wife; I do believe with all of my heart that doesn’t mean second choice or second best. But having his first wife prepare his dinner for him, and the rest of us (we alternated days), was more than I could stomach some days.

It’s not typical that a stepmom has to see her husband’s ex-wife prepare the same dishes she cooked when they were married. It made me feel like I wasn’t doing my job as his wife. It sounds petty, but I felt it very powerfully and personally.

Perhaps I’ll always have deep-rooted insecurities that only arise in extraordinary circumstances. Or maybe it’s just being put in this weird position.

I know that I’m my husband’s first choice today, and I know that it doesn’t matter who cooks dinner. And I also know that stepparenting is a complex, emotion-laden role and responsibility.

You don’t have to be roommates with your partner’s ex to implement the lessons I learned from my unique living situation. Remember to set boundaries, accept your role as #2, and allow yourself to feel the emotions that come with your unique role.

When you know where you stand and embrace your role and the boundaries you need in order to flourish in your role, you are better prepared for those overwhelming days. For more ways on how to set your boundaries and take back control, join us for our LIVE workshop!

  1. Gosh I have been DYING to read about this living arrangement! I totally get it… BM and I have had a much better relationship lately, texting with “girl talks,” sharing jokes, etc. But no matter how close her and I get (like I know you and Amanda are good friends), I will always feel a little sick to my stomach whenever she tries to be “friends” with my husband! So petty, I know, but it brings up all these emotions about being the second wife and the stepmom. I feel ya, Kristen! Thank you for sharing this personal story. You are an amazing mom!!

  2. Kristen, thanks for writing this! My husbands ex-wife was never good at the mommy thing, so she chose to move across the country from her child. As a result, when she would come to visit their son (about once a year) she would end up staying with us. People thought it was so crazy that I would allow it, yet I knew if she didn’t stay here she would have an excuse every day why she couldn’t see him….so it was best for him. It was so weird having her break our rules in our house! She’s was giving him anything he wanted even if it was something he wasn’t allowed to do/have. Like, I would be livid over it! It was weird how those “OMG, how dare you” moments popped up and it was definitely boundary crossing. Thankfully, the visits are over since our son is now grown. I’m glad to see I’m not alone in doing these kinds of things for the child even if it makes me crazy uncomfortable! Great post!

    • How crazy that we had the same experience! I’m so proud of you for putting the kids first. That’s really what matters. We can deal with being a little uncomfortable 😉 Thanks so much for commenting, Lisa! It’s nice to “meet” you 🙂

  3. I am so glad I found your blog! Everything I’ve read so far I’m nodding to and it’s making me feel like I’m not alone in feeling second best.
    I’ve just signed up to your free 5 day course and I am excited!

    Q. When you realised decorating your house was a boundary you needed to have, how did you implement it without feeling like you would come across as unreasonable and possessive? This is my biggest fear in creating any boundary with anyone, and have often just ignored my own needs to my detriment 🙁

    • I’m so glad we’ve connected, Ebony!

      I had the same fear (and honestly, still do some days!) but I told her what happened from my perspective, how it made me feel, and why it was my boundary moving forward. When she understood where I was coming from, it made it easier for her to respect the boundary.

      But just know that you are completely entitled to your boundaries and don’t need anyone’s permission to set them!
