Backstory
Ex and I were together 6 years, had our ds unplanned. There were numerous red flags but I continued with the pregnancy.
Relationship was "ok" he was/is a drinker which really crept in during covid. He cheated this time last year, that relationship lasted 4 months he came back tail between legs begging for another chance. I asked him (pretty much begged) him not to do that to us again, our ds was having issues with him just disappearing from our lives, said he was happy and wanted to make it work. Then in October, he went out cheated again and he is now living with OW and her 3DD 2 hours from us.
He has refused to do medation, hardly pays and the only time he wants to see our son is if he can bring his gf and her 3DD along.
The rare times he does visit on his own, he sits in my home "wanting to watch TV/film" doesn't fully engage with our son, goes to the shop to have a 'cheeky drink" and tries it on with me
Our DS had a GDD diagnosis 2.5 years ago, I and my son have worked so hard to turn this around in time for him to start school, he no longer needs a ECHP and will be attending a mainstream school, the only support needed is speech therapy. My ex never came to one appointment , never came with me to visit 1 primary school (this was when he was busy chasing skirt) during open days, didn't so the application with me, in fact has shown no interest in our son.
There's no much more, but it will be so long. Majority of my friends and family have been telling me to cut him off for a few years, asking me "what am I waiting for, him to turn into a decent father" even my therapist has suggested he will do more damage to ds than good
I have had 84 missed contacts in 2 years, in the last 3 weeks he's called him twice.
My son has now said "daddy doesn't answer the phone because he's angry at me" and "daddy doesn't want to be my friend, he's (the gf and her kids friend)"
Today, we have had another huge blow out, we spoke last week and we agreed that he would do more things with him on his own, then when son is comfortable (he still wants me to come everywhere) then to bring his gf and her children.
He's backtracked and said "I'll do what I want, she's my gf and I want her there"
I've told him to forget everything, he's not listening, I don't think she knows the backstory maybe if she knew she would understand.
He's also told me, that while he loves our son he isn't going to "bother with medation because he doesn't want to" and he will have a new family with her and have more children.
I said to him to you will just leave our son, not put in any effort and just have more kids? He said "yes, don't call me again"
He's known this woman and DD 7 months, and they have become his priority telling me "we are a family now"
AiBU for just walking away now?
He does nothing, and I mean nothing
Just wiped his hands and walked away
