DP and I have lived together for two years, I have a 12 year old daughter who lives with us and he has a son to his ex wife who stays with us every other weekend. The problems are that DP seems to hate anything that suggests me and DD actually enjoy each other's company. He comes down on her really hard if she does anything wrong (like leaving dirty clothes on the bathroom floor after a shower) but if it's his son he just picks his stuff up for him. A few weeks ago DD said something about her accent is slightly posher than her friends as she went to London once as a toddler. I just laughed and said "yeah, maybe" as a brush away comment and DP took me aside and started going on about how ridiculous it was that I agreed with her on that and did I realise what a stupid comment it was etc. I said "she's only 12 and I didn't REALLY agree with her obviously, it was just a throw-away response" so he started going on about how there's no wonder she's "Like that" when encourage her attention seeking behaviour!! It happened again last week, she believes she has social anxiety as she gets nervous in big groups. Basically she's just a little shy but as a pre-teen she tends to blow everything out of proportion. She was begging me to take her to the doctor about this social anxiety and everytime she mentioned it DP snapped "oh for fucks sake" etc. In the end I agreed to take her to the doctor well DP flipped in a huge rage about how I always encourage her, how its disgraceful to take her to the doctor when I know there is nothing wrong with her, its feeding her hypochondria etc etc. He then reeled off TO HER about two parties she'd been to and 2 days in town with friends plus a play she was in as a main part performed infront of a hall full of parents and told her she made a mockery out of realy mental health issues and she was nothing more than an attention seeking hypochondriac. She was in flood of tears over it and I had it out with him and he said he finds her impossible to live with and I apparantly encourage it.
I don't know what to do anymore, maybe I shouldn't have agreed to take her to the doctors but he over-reacts about EVERY little thing and DD is really starting to hate him.
