My partner has a step daughter, she is not biologically his but he's brought her up from day 1. He's been an amazing father figure to her and they have a very close good relationship.
She's now 10 - and lately I feel like things have become (what I feel) is inappropriate but I don't know if I'm just over reacting?.
She's started going through puberty, and wearing those non padded bras that girls first wear.
She stays over his house every other weekend to sleep, she shares a bed with him and she wears these bras and just underwear in bed to sleep, she is also open with telling him she's starting to grow hairs under her arms and on her private area. He also still bathes her when she has a bath.
I've tried telling him this is really inappropriate as she is now 10 and started going through puberty and there should be some boundaries, but he basically said I was wrong to feel the way I was feeling and he thinks she should go to bed in whatever she wants to wear. And every time I try and speak to him about this he tries to flip it around on me and accuse me of cheating or he would say he's gonna break up with me.
Am I wrong for feeling like this is inappropriate what's going on?
