This sounds a lot like my DP and his youngest, even down to the constant nits. He’d literally be sitting there picking them off her head and I wasn’t allowed to say anything
or it would be me “making her feel unwelcome”.
If we took the kids out and gave them a limit - eg you all have £10 to spend in the gift shop - mine would spend ages choosing and making sure they kept within the £10 and he would just get her whatever she wanted. Or if they all chose a pack of sweets she’d get a £5 magazine. It got to a point where I’d just say “oh DP is buying magazines if anyone would rather have one of them instead” but honestly it’s the main reason we don’t live together after nearly 10 years together, as even now they’re all teens, I couldn’t bear the favouritism and adoration.
I mean I love my kids, but his eyes just lit up when this kid walked in a room. The one I felt most sorry for was his other daughter, who was also desperate for attention but was closer to her mum. When we’d go out for dinner they’d both fight to sit next to him or on his lap etc and then spend the entire time monopolising his attention and he didn’t understand why I wasn’t that fussed about going out with us all together, but it really was just him & his, me & mine, like two totally separate families.
One time when I thought I’d really make an effort and take everyone out for a big trip to London I barely got to speak to him all day as they both held his hands and sat next to him the whole time. At one point he reached behind one of them to touch my shoulder and she turned round and licked his arm. Just total territorial marking!
These days I only choose to spend time with him when his DC are with their mum. It doesn’t stop them calling him for no reason when he’s here “Dad where are you, what are we having for dinner? I need some money. I’m bored etc” when their mum is supposed to be looking after them. One night we were out for our anniversary dinner and he had 14 missed calls from his DD as she’d just keep ringing and ringing until he picked up. But I know that’s on him for not having any boundaries. It used to piss me off that they just called for no reason every time we were out. And he would get annoyed by it as it made him feel guilty for being out, but I wasn’t allowed to be annoyed by it.
Things have improved somewhat as they’ve grown up. They have friends and boyfriends now so aren’t so dependent on him for their entertainment.
The sad thing is even as adults I can see that they will continue to impact my life more than my own kids. We talked about moving in together when they’re all older and his first thought on it is “I want my kids to feel welcome whenever they want to come round, I want it to be their home too”. We have 5 kids between us - if they’re all welcome all the bloody time, with their partners and kids of their own, I’m moving out
He said “I’m sure if your DS wanted to pop in for a cup of tea on the way home from work you’d be delighted”. Yes once a week. If he does it every day I’ll be telling him to get a life
