Just got home from a week away with DS 15, DD 13 and DP. DP has very recently moved in full time temporarily until his work accommodation is ready in November. Kids are typical teenagers but generally really good. Week away was tense to say the least. DP was increasingly frustrated by DD who is high energy and can be loud. After dinner one evening she was chatting and joking around quite loudly. DP got quieter and quieter and then suddenly yelled Shut Up and stormed out the room. He didn’t speak to anyone for the rest of the evening and pretty much gave everyone the silent treatment the following day. It feels like a massive red flag and I’m thinking about asking him to move out. I’m not sure if I’m overreacting but, to my mind, his behaviour was unacceptable. When I spoke to him about it he told me he didn’t feel he’d done anything wrong and that if someone spoke to him that way he’d be fine with it because he’d ‘deserve’ it. WWYD?
