My xh has decided I am "legally obligated" to let him know when I am absent from my home to go to other places within the UK (i.e. visit friends for a night). He is a very absent father, but likes to call his DC daily (when he doesn't have more interesting things to do), and if we don't answer will call non stop for 2 hours, text, call my parents, email etc.
It was a very emotionally abusive relationship, and I find it hard to react rationally or set boundaries down with him as basically I am terrified of his reaction and I get very anxious. He feels that if I don't tell him where and when I am away, he is wasting his time and energy calling. I feel like it is very controlling and abusive that he needs to keep constant tabs on us, and it is very hard to emotionally detach with his demands and constant calls/emails. What is a reasonable or sensible way to deal with this? I have avoided dealing with it for too long, and also feel guilty that if I do the wrong thing I am punishing my DC.
