Ex and I split around 4.5 years ago now. He was emotionally and financially abusive. He made my life hell for a long time after we split. I've learned to deal with him finally after some counselling. I let him off with a lot of things in the early days because I didn't want him to kick off. Now I'm not so tolerant. His CMS payments have just been reviewed and have been increased (not by lots, around £45pm) and he is furious. He honestly thinks his overtime should be his and none of it should go to me (I don't make the rules). Now he is telling me that they will have to take it out of his wages because he cannot afford it (so basically he's refusing to increase it) and that he is going to be selling his car and house. He always threatens these things, I assume to make me feel bad for him. He said he would speak to me about it but then never did, deciding to try to guilt me instead. If he had spoken to me like an adult I would have happily come to an arrangement with him if he agreed to have the kids more in the holidays (he has had them 2 extra days this year). he only has them every other weekend. I am so conflicted about what to do if he continues to not pay the full amount. Is £45pm worth the aggro I will receive when he finds out I've contacted CMS. I know he will make my life hell again and I'm only just finding myself in a good place. On the other hand, why should he get away with it?
