Overly involved brother-in-law

I currently live with my partner and his twin brother. My partner and I met a year before they bought a house together. We got serious quickly and wanted to settle down, but he was already in the process of buying a house with his brother—a plan they had been working on for years, saving for a deposit, going to viewings, and making offers. When their offer was accepted, I realized I wasn’t entirely comfortable with the situation. At 33, I wanted children soon and a home of our own.

I expressed my concerns, but my partner explained that he had promised to help his brother buy a house and couldn’t break that promise. He said it was only for three years; after that, they would sell, and we’d get a place together. A few months later, COVID hit, and I moved in so we could be together during restrictions. At first, it was tense—I felt like an outsider, his brother resented my presence, and their family and friends seemed to downplay our relationship. It was all about “the twins,” and I was on the sidelines.

After a few difficult months, I moved out, and my partner and I nearly broke up. But life outside the relationship was lonely, and my partner worked hard to win me back. His effort made me realize how much he loved and cared for me, which deepened my love for him. We reconciled, and my relationship with his brother improved. A year later, I became pregnant.

However, things became strained again after our baby was born. His brother became overly involved, giving unsolicited advice, acting like an expert, and making comments about being a “second dad.” Even their mother made a hurtful remark implying my child could just as easily have been his brother’s. His brother would talk about my DD to others as if she were his, saying he could “experience fatherhood” through her. This upset me—I chose my partner to have a baby with, not his brother.

I wanted to move out but found it overwhelming with a newborn. Over time, things improved slightly as my DD grew older. His brother plays with her a lot, which I appreciate, but he often oversteps, trying to parent her in my presence—worrying about her meals or hydration when that’s our responsibility. Sometimes I address it, but other times I’m too tired, which likely sends mixed signals. Constantly reminding him is exhausting.

Now, I’m pregnant with our second child, and my desire to move has intensified. The dynamic between the twins is difficult to navigate—they work together, have always lived together, share friends, and even have a joint bank account (while my partner and I don’t). Small things add up, like Christmas cards addressed only to them or joint presents for their family, which leaves me feeling excluded.
While his brother helps with our DD and my partner relies on him for support, it frustrates me that my partner hasn’t fully experienced solo parenting. This lack of experience made him less empathetic when I struggled early on. Recently, his brother sent me an article about foods to avoid for children, something I doubt he’d send to other parents. I can’t tell if I’m being overly sensitive due to pregnancy or if my feelings are valid.

I don’t feel like we’ve had time to bond as a family of three—it often feels like it’s either me and my DD, or me alone while my partner and his brother bond with her. My partner understands how I feel and has agreed that we’ll move out this year. Still, I can’t help but wonder: am I being too harsh, or are my feelings reasonable?

You knew exactly what you were getting into here. You chose to move back in. You chose to get pregnant a second time.

It brings to mind that quote that the definition of insanity is doing the same thing over and over again and expecting different results.

YABU for expecting different results.

This. As you have found out you cannot live this way. And why should you? Either you dh and dc move. Or be miserable until you end up divorced.

Ok, I will make this as simple as possible for you.
OP's partners twin brother did NOT ask for his brothers girlfriend to move in with them and get pregnant twice. He may not have been happy about that
Is that clear enough now?

No, that's really harsh. Maybe op was absolutely in love with this guy and enmeshed and didn't expect it would go this way?

Gazelda · 10/12/2024 15:51

BIL bought a house with his twin, as had always been planned.

A girlfriend moved in very quickly , moved out and back in again. A baby arrived. another is on the way.

I don't think he's been treated very well, not his home and life plans respected.

Your DP has been unfair to both of you.

They sound a little too involved. And I'm not surprised you resent his input into your parenting. But your DP has caused all of this. BIL has simply gone along with his twin's choices.

I'd move out if I were you. Get your own place with the children. It's then up to your DP to decide who he lives with.

JFDIYOLO · 10/12/2024 15:49

This is ... weird.

Yes, you did walk into every aspect of it with your eyes wide open so it's not like you were deceived.

The kids will soon be noticing - or their friends will soon be telling them - how incredibly weird it all is.

I don't quite know how to ask this, but ...

OP, are they identical?

Is there the remotest possibility that they might be ... sharing you? And you haven't noticed? Especially with their mother's equally weird comment.

Just read a book called Touch Not the Cat where this happens, so it's probably high in my mind.

Personally I'd be going all out to get the break made and start your independent life with your partner and children. This must all surely be getting in the way of his brother finding a relationship of his own?

Minerbirdy · 10/12/2024 15:49

You experienced this first hand and still went ahead with it, and you’ve it’s happening again…..?

ATastingMenuButItsAllCrisps · 10/12/2024 15:49

@SalsaLights OP is legally single, choosing to live in a property owned by these two blokes, zero legal protection.

PartyLlama · 10/12/2024 15:47

Your partner sounds like he is married to
his twin....I'd rather be a single parent

Terrribletwos · 10/12/2024 15:42

I had to decipher your post as it didn't make sense initially. Still not sure what you mean? The partner chose the wife? Confused.

Hoppinggreen · 10/12/2024 15:37

Terrribletwos · 10/12/2024 15:27

But what does the partner think about this? Surely, they were involved?

But the partner chose this BIL didn't

SalsaLights · 10/12/2024 15:28

You need to move out.

You knew they were enmeshed when you moved back in. It's not going to change and it's not going to get better whilst you still live there.

The only way to put boundaries in place is to live somewhere else, and be very clear on the fact that you married your H, not the pair of them.

Terrribletwos · 10/12/2024 15:27

Hoppinggreen · 10/12/2024 15:12

He was buying a house with his brother like they had always planned and then OP moves in with them, gets pg, moves out, moves back, gets pg again.
Not many single blokes would be happy about that

But what does the partner think about this? Surely, they were involved?

LavenderSquid · 10/12/2024 15:25

Gosh. Their relationship sounds very enmeshed. Like you are the third wheel rather than BIL. It was a bit mad to move back in with them when you got back together really, let alone bring kids into it.

You need to move out asap. With or without your DP. He can follow if and when he breaks up with his brother. This situation is very odd and I think you've lost sight of that if you are questioning yourself.

GabriellaMontez · 10/12/2024 15:23

Twin relationships can be very complex. Especially male twins.

That's not going to change.

I don't know how you tolerate it. It would drive me insane.

Yanbu to leave. Or continue a relationship living separately if you want.

You were crazy to go back there.

Snoopdoggydog123 · 10/12/2024 15:19

So you've sleep walked into 2 kids?
What did you think was going to change by doing nothing?

He doesn't want to change so why would he? Because you want him to?
You're not his number 1 so he's not going to make himself and brother unhappy for you.

So you'll either have to suck it up like you have been or use your own steam to do something about it.

Hoppinggreen · 10/12/2024 15:12

Terrribletwos · 10/12/2024 15:02

Not so sure about that, the brother sounds way too involved. If he doesn't want to be so involved he would be encouraging the other brother to move on surely?

MammaTo · 10/12/2024 15:08

I don’t think your BIL is completely to blame here. I think it would be hard to not feel some kind of parental pull to your twin siblings child who lives in the same house, until you move out he is like a third parent.

whatnow5 · 10/12/2024 15:02

You’re always going to play second fiddle to their twin relationship. (I’m not saying this should be the case, but it is.)

You can move into a house with your partner and children and hope that will solve things, or you can split up, and have lots of people to mind the kids for you and let you have a life.

I would pick the latter, as ultimately, if your partner wanted to live with just you he would be by now. He is picking is twin over you, and will continue to do so. Is that the life you want?

SapphOhNo · 10/12/2024 15:02

What a bizarre situation for you to walk BACK into and then bring children into it. Take ownership of your life.

Terrribletwos · 10/12/2024 15:02

Hoppinggreen · 10/12/2024 14:58

I actually feel sorry for your BIL, he probably doesn't want any of this.
However, your partner put his brother first and will continue to do so, none of this is a surprise to you so I don't have a lot of sympathy

Nn9011 · 10/12/2024 14:58

Your partner and his brother are enmeshed and I'd encourage you to do some research about those types of relationships and make some difficult decisions. Your partner and his brother are substituting each other for a romantic partner and you are providing them with children. I'm not saying they actually want to be in a relationship or anything gross like that but similar to parental/child relationships that go wrong like this, somewhere along the line the responsibilities/shared goals and experiences/expectations get put on each other instead of a romantic partner.
I honestly doubt things will ever change, the only way it could begin to heal (in my opinion) would be if he actually took steps to move out.

Although yes perhaps there is some accountability on you for ignoring red flags, there's no shame or blame for being in this scenario. Many people end up in similar circumstances only it's PIL/Partner, there's many posts on here about their mil being a 'boy mum'. I say that just because I saw someone saying you walked into it - no one walks into a situation like this because they can clearly see the outcome, we're all human.

As I say, I'd encourage you to do some research on enmeshed relationships and perhaps seek some individual counselling and then review your situation. Don't fall into the trap of being worried about the children - better to be happy apart that sad/angry together if it comes to that.

YANU but at the same time you walked into this situation with your eyes wide open.

It wouldn’t be for me. What does your partner say when you discuss it? Are you back living with them?

^^ This

You walked out once. He got you back

And then it all just carried on

Why?

cushionfiend · 10/12/2024 14:54

It's been well over 3 years now, so surely time for your partner to be buying a place with you and moving out? Personally, I would be giving an ultimatum by now.

vibratosprigato · 10/12/2024 14:46

I don't blame the BIL for being a bit too involved considering the nature of his relationship with his brother, and the fact you all live together.

How does your partner respond when you talk about buying a house together? Can his twin afford to buy him out or would the house need to be sold? You need to know that there is a definite end date to this situation before you can decide whether or not to stay.
