Currently still living with stbeh due to financial situation and likely to do so for a year. Separated since end of January.
Stbeh has introduced dc (6 and 8) to new gf. She comes to the house 2 evenings a week (while I am at a hobby). He goes to hers 3-4 evenings a week and stays over.
My main issue is that he basically dictates weekend time - he'll tell the dc what they're going to do and then I either have to go along with his plans or look like the mean one. He's having the dc over at her house for sleepovers (she also has 2dc) which I'm not particularly comfortable with but once he's told the dc there's not much I can do.
I'm worried it's all really bad for the dc. The relationship is only 2 months old.
Is there anything I can do? I've tried discussing it with him and thought he'd understood but then he planned 2 sleepovers this weekend (Fri and tonight) and last night they were all at a wedding (sharing a family hotel room)
