After many previous posts under a variety of names, H finally moved our three weeks ago. It was definitely the right thing to do, and reasonably amicable.
He's moved in with a woman he's known four months but is apparently 'very compatible' with. All very nice and cosy for him.
I work weekends away from home, so H Has agreed to continue as we were when together and be with the kids, in their home while I'm away.
But for three of these nights he has taken youngest DC to stay at OW's house, slept over, takeaways, bbqs.
Each time I have heard about it after the event and I really don't like it.
DS is 11, but I think emotionally younger, and says he likes going over there, he gets on well with her much younger son, etc
I've tried to tell H I'm not comfortable with it, but he basically says 'tough, I'm happy, he's happy. Suck it up.'
Do the 'rules' about introducing new partners to your kids still apply at that age, do I just have to suck hard?
