My ex didn’t see our children for 2 years, he came back in contact last year and has seen the children 4 times in a year. The last time he saw them was early may. I would like to block him as it seems contact has stopped again. However I’ve been told this will make me look bad. So do I really need to keep in contact with him even if he isn’t seeing our children? He messages to ask things to me and I don’t really want to speak to him since he isn’t involved with the children. I don’t just want to ignore him as I would rather not receive the messages.
