DP feels he is competing with his ex over SD. It’s a never ending battle of black mail from mothers side & emotional distress. She only has one DD, whereas DP has 2 DC’s with me. Mother is ill & uses this as weapon to pull DD towards her. Constant ‘I miss you. I hate it when you leave me’. Never ending FaceTime (oops lost/broke charger happens regularly). DSD is staying at ours on Friday night, she is 12. She has complained that she always has a friend over on Friday & has been a mardy bum as she still wants to see friend on Friday. So DP has said she can come to our house - without asking me if that’s ok. I don’t think it’s ok. I don’t have many evenings at home in the evening. My favourite thing about being at home is that I can get my nighty on and relax, as soon as I know I am done for the day. I’m cross as now we will have a stranger in the house. I won’t be able to relax, then the parents will be coming along to collect friend, more strangers. He didn’t think I’d have a problem but I really do. I wished I was working. AIBU?
