Her half siblings are her blood relatives. If you had more kids with your DP would you say they weren’t her real siblings? If she doesn’t call them that then it’s clear you’ve been saying that to her.
they’d take more of a dim view towards you than him considering you’ve been blocking him having more access, hell I’d say he could even prove that you’ve tried to alienate her against her actually siblings.
maybe he couldn't afford it before, maybe he thought (naively) you’d do the right thing by your daughter, maybe just maybe he’s getting all the evidence to prove parental alienation
If people (one/maybe two in here did before they read all your posts) are telling you he won’t get 50/50 have you considered they are doing that because it’s what you want to hear and not want you needed to, as they’ll know how you’ll react?
he isn’t just as much in the wrong at all, in fact I can’t see what he’s done wrong. so he works when he has her sometimes, so this means his wife (her step mum) looks after her, why is that not okay when at the same time it’s okay for your DP to look after her when you work? It’s clearly one rule for you (I can do what ever the hell I want) and one rule for him (you can’t do anything unless I say so)
no you posted hoping people would agree with you and say yes he is a dick and you are right etc, when in reality we can see that you are the issue. You are the one who up until now refused any weekends.
If you truly truly were for dads having equal rights you wouldn’t have prevented weekends before or reduced his week nights in lieu of one weekend a month.
