My friends girlfriend hit him and strangled him and he is blaming himself

[CatStacks]

she is jealous because he has had sex with a lot of girls she knows.
He use to be with her but they broke up years ago because he cheated and had a kid. He then got into a relationship for 5yrs and had another kid
he broke up with her and is now baxk with the hitter girl

so him and her went abroad and there was a girl who was there who he had sex with

the hitter girl then strangled him and punched him in the face in a club and he left and come baxk to the UK.

now he is upset everyone is getting onto him aka her sister and mum and he blaming him

he phoned me upset and depressed because he is blaming himself

what do you think if this?

I told him this relationship is toxic and she is abusive but he is blaming himself but he keeps saying stuff like she is a good girl and does a lot for him

They both sound pretty grim. But violence is never acceptable. Not sure whether the police in this country could do anything about it - but he should certainly talk to them.

that's what I said regardless of what he has done to her the moment someone hits you the relationship is done.
He is bipolar and depressive but he is addicted to this drama filled girl who won't ever get over her insecurities
I don't know how to help him see she is wrong, he has this queen image of her in his mind that she is perfect.
