DP and I have been together five years. I have one DC from previous marriage and he has three DC from his previous marriage that are with us every other week. No kids together. The kids mostly get on and play well. There is some unhealthy competition with my DC which I don’t like and his kids are allowed much more screen time and watch age inappropriate things at their mother’s. His kids also have more care needs (ADHD, neuro-diverse, etc) than mine. DP and I try to split the cooking but he is easily overwhelmed by his kids (he is also ADHD and ASD) and things run to chaos under his control (laundry piles everywhere, mess, wrappers discarded, etc). I’m not a neat freak at all but the mess drives even me crazy (things like touching handles with filthy hands and not cleaning toilet bowl after a poo). I am often the one laying down rules, enforcing boundaries because DP much more relaxed. The house gets wrecked when they come over (it is my house). We both work full-time. DP and I used to enjoy time together but increasingly in evenings he just games and I go to sleep early. Basically: I am tired and feel like life would be easier if it was just me and my DC. AIBU to think that no matter what happens blending families never really works and I will ultimately be the one sucked dry and drained by this situation, with more net harm than good in the end? I sometimes miss the days when it was just me and my DC and it was peaceful, but also I think I would really miss my DP and my DC would miss DP’s DC. I don’t know whether it would now be more harmful to my DC (who is about to start secondary) to lose DP and DP’s DC - or better for him (and me) in the long run. Help.
