been with my partner 3 years, recently got engaged..having regrets now. i have two sons from a pervious relationship ages 8 and 6 and he has one son aged 8. my sons live with me. he has his son every weekend. we havent moved in together as a couple but he wants too soon. hes fantastic with my kids when its just us. he brings his son here every 2nd weekend and this is were the issues start. 3 boys for the most part get on great..his son has an issue sharing so we generally just share our toys etc. i completely understand this will take time and done ever mention it or expect it. i encourage him to spend every 2nd weekend just the 2 of them as he needs time alone with his daddy. my issue is with my partner no matter what we do is never good enough and never appreciated. we share everything my kids think his son is brilliant they are so excited when hes here..but there is always something to complain about or some reason to run my kids down..example. this weekend all 3 kids playing xbox was his wee lads turn and my pair moved 2 meters away from him to play with a toy, he barges in forces his son to stop playing xbox and demands they give him the toy they played with..and was ragin because they shud have f;ing sat and watched him play..if they move away from him or take any attention away from him he gets bitterly annoyed...same thing happens later on and his son and one of mine move away to play and he doesnt bat an eyelid..all that matters is all attention is on his son and mine are villified if they take 5 mins to themselves if hes here..is this normal..we love having his son here but the dynamic with his dad is really ruining it constantly picking at how we can be better for his son.
