I don't know where else to turn. I have no children of my own but my DP has 2 children (11 and 7) from a previous marriage. The children are generally fun to be around. I think they are pretty normal children so they are demanding and sometimes annoying but I have been surprised at how easy it's been to cope with all of that (I genuinely enjoy their company and have grown to love them over the past year).
The thing I can't cope with is my irrational anger with their mum and I am afraid that it will have an impact on the good relationship I have with my DP.
My DP is so afraid of damaging the precarious (in his eyes) relationship with his children that he rarely stands up to his ex (who seems to be quite volatile).
I am angry because in my eyes she seems to have the life of Riley (please don't shoot me down for that). One example from a list of thousands... My DP was supposed to take both children back to their Mum's tonight (have had them since after school Thurs). On Friday night their Mum called to ask if he would keep one of them o'night tonight and take her to school tomorrow morning as she'd like to take the other child to the cinema tonight and, as she's off school tomorrow, they'd like to have a 'lie in'. All I want is a child-free evening to enjoy a glass of wine with my DP.
How can I get rid of this irrational anger (and I'm normally a fairly placid individual)? I am supposed to be moving in with DP later this year and I don't think I can do it untill I have this under control.
Any tips at all to calm me down and help me manage the situation for the long-term would be good. Thank you.
