My ex hasn’t had contact with our children in 2 years, I made a stupid mistake recently by allowing him to talk to them on the phone as he got in contact again recently asking to speak to them. I’ve decided that too much time has passed and I don’t really want to let him back into their lives again after such a long period of absence, it would be like letting a stranger in. I felt that as I have no family or support I stupidly needed him but he doesn’t actually look after them anyway. As I said I feel too much time has passed now and he feels like a stranger. Can I refuse contact? He would never take me to court so I don’t need to worry about that (I should also add this isn’t unusual and he has previously gone a year a few times without seeing them this has just been the longest stretch of time) has anyone had an ex have contact after such much time and did it work out or were they just the same?
