Hi so my partner has his children nights a week, these 3 days he works and he expects me to look after the kids as well as my own. Iv told him to change his days so he’s at home but he won’t doesn’t want to cause an argument with kids mother. Kids even say it’s pointless coming to see him when he’s not here but there mother makes them stay, I do everything for them cook, clean, iron uniform, pack ups literally everything plus work part time. He never watches my kids causes arguments said he’s been at work all day, I never ever get a break from my kids or he’s, even when I’m ill he never says I will tell kids to stay at home this weekend. He never asks if I have plans or if I mind watching them it’s just expected. It’s literally draining me out and everytime I mention anything he causes an argument, am I really been selfish? He jumps when kids mother says so but yet doesn’t think of me.
