My babies father doesn't seem too bothered about him, do I give up? 📱

My ex husband (26) , the father of my child who is now 4 doesn't seem to generally care or ask about our child.

The babies father instead has moved on since I broke up with him while pregnant and is now living with someone else as his old living arrangements in the past left him desperate for a place to live giving him no other option but to move in with his girl straight away, she has 2 daughters of her own with another guy who's still in her kids life.

Son here's the thing, my ex hasn't ever seen my son in person because he was abusive towards me during our marriage that's why I left. He was emotionally abusive.

Facts

- I always have to be the one to call him

- he never generally asks or cares to check up on our son

- he's never asked about his health, his progression of growing up or anything

- he doesn't pay child support and never has

- when I mentioned about child support he said he would only if I begged and showed where the moneys going

- he insults me infront of him sometimes

-doesn't answer his phone ever, only very rarely

-lies about everything

He generally is coming across like more of a deadbeat father than I originally thought, honestly.

He never appreciates or has said anything about how well I'm raising our child. He never takes an interest in our sons likes and dislikes he only cares about whatever is important to him.

I've don't it before where I've not spoken to him to wait for him to reach out to me first and it usually takes around 3 weeks of silence before he FINALLY asks to speak to our son.

Luckily our child doesn't understand what's going on and honestly at this point I'm tempted to just call it a day and just prevent confusion for my child by raising him alone and letting my next serious partner be a better dad role model to him than my ex will ever be... Is that a good idea?

In the mean time I'll be civil with my ex if for whatever reason my son in the future wants to know his birth dad but I know that once my ex has another biological child of his own, with the woman he's with now... Then he will completely forget about us 1000%

He also has cheated on his current girlfriend and she doesn't know about it.

I'm doing everything I can go adapt to this lifestyle not for one day have I ever been a proper family and its heartbreaking, its something I've taken 4 years to get used to though.

Me and my ex aren't yet divorced as I cannot afford it and also I have to wait another year before I can process it through.

What do I do.......?
