My DH and I have been together about 9 years and he has a 12yr old dd from a previous relationship. We're probably pretty lucky, we've no issues with his ex and my dsd is really lovely, we have her every other weekend and extra in the holidays. What I'm struggling with is my husbands behaviour when she's around. He is so over excited to see her he's like a child! Asking her so many questions she can't even answer them, going in her room to chat for 45mins after I've said it's bedtime and asked her to get into bed. Anytime I discipline her eg:- ask her to chew with her mouth shut or not be on her phone during dinner he comes straight to her defence - again in a really childlike way that's confused the hell out of me. I get that he's probably worried about her growing up and not wanting to spend as much time with us, but his behaviour has started to make me not want her to come - and it's nothing to do with her at all! Tried talking to him about this but he got really defensive. Anyone been through this before or have any tips? It's really starting to cause a wedge - I just want him to behave as he does when she's not here and am probably being a bit over sensitive about it. Do I just need to try and ride this out?
