Ex trouble

[Avpixie27]

So i got dumped back in 2016 by my sons father and then this year found out he had cheated on me for the last 2 months of the relationship. I spent a year single in a new flat to fully get over him as he was emotionally and mentally abusive to me to the point i had to go on anti depressants for almost killing myself. Ive now been in a relationship with a great guy for 7 months and he is great with my son. Hes only seen him a few times but my son adores him and plays with him, he even got him birthday and christmas presents that he loved. But every time i hand over my son to his father he brings up my new boyfriend and has to get digs in but then says "i have a right to know as its my son" but i have reminded him that hes from a split family himself and neither of the parents interacted after the split and neither brought up or even met the others partner to this day. Saturday my mother called me to tell me he had showed her my boyfriends facebook profile and researched that he had had a conversation once with one of his friends over 2 years ago. Its seriously annoying and im fed up of him always mentioning him. Ive told him to drop it as i dont care about his girlfriend (the one he cheated with) i said id only want to know if she does something to my son. Any advice?

Ignore him. He wants your attention. He’ll get bored when he doesn’t get it. Ignore. Hand over your son, shut the door.

Get your bf to block him in social media

Block him yourself and ignore any verbal comments he makes just smile politely

He is sneaky he starts by saying he is concerned about my son then says "and then he mentioned boyfriend and how his house is small" and i say "ok theres no need to go there" and he says "im just bringing it up as he said it and im concerned as his dad" its all bull as my son doesnt just blurt his name out and hes never been a dad to him ever so its cause he wants to control me. Thats a good idea i may have to do that

So when he starts talking about a concern, look at himself blankly and stay silent until he continues on with making his point. Let him make his point then say to your child “okay, bye son, mummy loves you” and close the door.

Ah small house but large penis.
Smile and close the door.
Stop engaging, just say bye and walk away. Close door and ignore.

Just ignore him, clearly he is very materialistic. My ExH has spent amounts living in houses and sneering at us for living a house with only a number. DP has a small 'Lego house with a number' as ex put it, but he is a thoughtful caring person that ex has never and will never be.

You have to shut it down.
He starts . Say well Ds is fine . Just had breakfast whatever appropriate bye Ds . Kiss and on his way . Do not tell him anything personal . Anything he knows will be used against you.
