I have DC with my ex. Since we broke up 4 years ago he has never bothered with them. For the first year after we split he was completely absent, he came back after a year but left again. A year after that he came back again and did the same. Since we’ve split he’s never once had them over night or even taken them to his house. Last summer after being absent for yet another year he got in contact again, literally begged to be a dad he had to go to some lengths to get in contact as I had blocked him on everything and changed my number. He begged to be involved, blamed mental health for the past and asked to be part of their lives said he was wrong etc etc, due to the pandemic I thought well life is too short and maybe it’s made him realise, well no. He saw them for a few months then just stopped seeing them again with no explanation! We’ve spoken about it but I get nothing back from him, he has every excuse in the book, but never makes plans to see them. I finally snapped and said well as you’re not seeing them again anymore I’m no longer going to be responding the any messages. And that’s it, nothing No response . I’m annoyed at myself for letting him back to see them again. I don’t understand why men do this? Why don’t they just stay away? He must have known he wasn’t going to hang around, I just don’t get it!
