I’ve been with DP (living apart) for 2 years. I can feel he wants to blend our families soon - no idea if saying no would mean the end of our relationship - but I have tried this before and it was a disaster of catastrophic emotional consequences for all the children involved. I have a DS10 whose dad I left at 4 months. We moved in with my ex and his kids after 18 months when DS was 4 but it all ended in disaster 18 months later. I have made it clear to present DP that I will never put DS through that again. He has two DS, close to age in my DS, but very different in personality and my DS does not want to spend much time with them (he has loads of pals from school who have much more in common with him). I am adamant that I will not ever put DS through that again and I try to emphasise the adult relationship we have to DP. I want to see DP when no kids are around and have a solely adult connection but he likes to spend time with us and bonds with DS over things that his dad isn’t bothered about. AIBU to say to DP that we need to keep to adults only and he can only see me when I don’t have DS? And that we will never have more than this until (and maybe not even then) until after our kids have flown our nests?
