I'm sorry Frog, some days are impossible. I hate that we have this in our lives. Life with a narc is incredibly destructive, but what ties me up in knots is that they are so oblivious to it.
If I stop XH coming into my home he will never have the children.
I have also got fit, have a boyfriend, good friends, lovely children who are an absolute credit to ME. If I don't let XH in, I never get a night off and I might as well end my relationship. The arrangement is XH stays over one night, the last weekend of the month, during term time. That works out at about 7 nights a year. I get to spend the night with my (very patient) boyfriend. He doesn't stay here. my youngest still sleeps in my bed, has done since he moved out. She needs a relationship with her dad more than any of the others, she's had counselling, is quite a quiet girl. She hates to be on her own, anywhere at any time. I can't introduce my boyfriend because I don't want her to feel any more insecure that she already does.
I have no family nearby. XHs family are half an hour away, but they don't help. I don't blame them, XH doesn't include them or feel the need to facilitate the relationship of his children with his family. He sees them a lot on his own, but it doesn't occur to him to take the children.
I know he needs to have the four DCs at the same time in his 2 bed flat (he didn't consider a three-bedroomed, didn't want to 'rattle around'). He also moved around the corner. He did this so he had a sense of being close by, so he could 'pop in and say hello'. Therefore not having to make any effort. It isn't home to them, they don't have their own beds. I told him to take a big chest of drawers when he left so they could at least have a drawer each. He refused.
I feel really sorry for his gf (OW). She's lives miles and miles away (he travels a lot for work, he's her boss). Poor woman doesn't know what she's got herself into. I genuinely feel for her.
