Do you understand that his actions sexually while you were pregnant put you and your child’s LIFE at risk?!
He’s lucky you’re even letting him be a co-parent!
You would be doing yourself and your son NO favours going back to this selfish, destructive, irresponsible twat!
If he genuinely wants support to stop using prostitutes and drugs there are plenty of avenues he can get that help from IF he was serious. I think it’s far more likely he’s desperately trying to win you back and will say anything but doesn’t mean it.
I have an 18 year old dd and quite honestly any 30 year old man taking an interest in her I would view with great suspicion in the first bloody place - she won’t give anyone over about 22 the time of day anyway, she and her friends refer to such men in the most derogatory but probably accurate terms!
And yes - he bought you! I’d say he likely at root thinks of you as little more than his own personal prostitute given how he treats you (and I mean that as a reflection on him not you!)
You can and should do better for yourself and your son - and I don’t necessarily mean a better man, staying single at least for now is a valid and powerful choice too.
And yes, I would say you need therapy as I dread to think what made you vulnerable to this man, sadly I think I can guess at possibilities.
I’m also a single parent I know how lonely it can be at certain times but honestly you’re better off alone than with a twat!
And actually entering any relationship when you’re lonely and desperate tends to mean you’re making poor choices relationship wise. You can’t have a healthy relationship with someone else until you have one with yourself - cliche but true
I wouldn’t be allowing Ds to be there overnights because of the drugs. This guy is too self absorbed to worry about his child perhaps accessing them or staying straight while he has care of your child.
“My mum left me as a child and I think the low self esteem stems from that. I have emailed a therapist last night to organise counselling. “ I thought something like that would be involved.
Drugs and alcohol don’t make someone do things they ordinarily wouldn’t consider, they just disinhibit them.
Your own father has some deeply worrying opinions - another thing I thought would be a factor. Quite honestly any decent father who’s dd had a 30 year old sniffing around them at 18 would have had stern words with that 30 year old!
A lot of therapy needed I think.
