I broke up with DS20's Dad just after DS turned one, and this is something that DS finds incredibly difficult.
DS has struggled with his mental health since hitting puberty and was diagnosed with ADHD at age 17. He finds the relationship with his Dad difficult and has often expressed the opinion that they would be 'closer' if we had all stayed together as a family.
I have always been very careful not to say anything negative to DS about his Dad, as I know how harmful that can be to children whose parents are separated. When he was small, DS would ask things like 'do you love Daddy' and I would always reply along the lines of 'Daddy will always be very special to me because he is part of you'.
I'm now not sure if this was the best approach, not least because his Dad did the opposite (he spent the whole of DS's childhood deriding me as stupid, selfish, a bitch and a bad mother). I think it's left DS with the impression that I broke up with his Dad for no good reason and just didn't care about DS enough to keep us together as a family.
The reality is that I tried my best to tolerate being in a relationship with his Dad for nearly two years but cracked when I saw how much his shitty, abusive behaviour towards me was starting to affect our one-year-old son. I broke up with him to protect DS from growing up in the kind of unsafe, abusive environment that I grew up in. It made my life a lot harder in a lot of ways, at least in the short term, and I got a lot of shit for it but I have absolutely no doubt that it was the right thing to do.
I'm now wondering if it might potentially be helpful for DS if I told him this - or if doing so might make him feel worse.
Whenever he visits his Dad, he ends up feeling really down. Ideally, I'd like him to know that this isn't his fault - it's because his Dad isn't a very nice person, and he doesn’t have to see him if he doesn't want to.
