Why would you want to give it another go with an abusive prick who uses seeing your son to manipulate you into taking him back, after he’s been an abusive prick?
You do realise the whole marriage would be nothing but him being an asshole and you trying to fix him by diminishing your own needs and making yourself small right?
You mean he doesn’t want to pay the bills?
Look, put a claim in for child support asap and see a solicitor about what you need to divorce this loser.
Because he is, a loser.
He doesn’t respect you. Infact, he has contempt for you. Calling you a bitch and waking your child like that is abuse to the child too you know. No child should be raised in a household where their father abuses their mother. It’s the sort of thing children are taken away from homes for, btw.
I know you want him to see his son. And so does he. And he’s using that to try manipulate you into taking him back.
Honestly the less contact men like that have with their children, the better. Bullies don’t belong around kids. And before you say “oh but he’s great with his son”, no, no he’s not - because he abuses his son’s mother. So he’s a shit role model. And a shit person.
Please start choosing YOU. You do not owe anyone to take this jerk back. And no amount of love or you trying to appease him, will fix him. He is a cup with a hole in it.
What is the housing situation?
Can you afford to move to your own place?
look into what financial entitlements you are due. See a solicitor about what’s needed for divorce and don’t tell him anything until you are clued up. Be aware he means you harm. And this will increase when you decided to leave. But we do not stay with bullies and we certainly do not take back manipulative bullies who use their son and even threaten the roof over their sons head in order to get you to take thr, back and keep tolerating their shit.
