I cut contact in February with my son dad. He sent me 2 letters one about how me and him will be strangers again and that he loves me and for the universe to bring us together no mention of our son. Then he contacted me cause I ignore the first one and then messaged me off his relatives TikTok saying I’m not alone and he loves me and always will so I messages saying you’ve not mentioned your son. So then I had a second letter saying how much he thinks and misses us both and how he wants things to work out he’s an alcoholic why I left, then I sent a letter back basically saying how hurt and how much I want him to get help blah blah, then the 3 letter basically told me to put my childish emotions to the side and he’s going to move on for the future and that includes his son. He hasn’t seen him over month and half and he’s a potential harm to our son. I can’t go back to him but I feel sorry for him but he won’t help himself! What can I do??
