Agree. Or she did something to make him jealous. My abusive partner terrified me on several occasions when he thought I had talked to another man
I believe Reeva had met up with an ex boyfriend just 2 days before (that Oscar claimed he was completely fine with).
So, yes, jealousy plays a big part as well.
DH can't work out why he killed himself though. I would say to avoid being sent to prison.
There's a sickening video via Facebook live of a man covered in blood after killing his wife, and warning other women to not irritate their husbands.
There's Jeremy McConnell (who put Stephanie Davis in hospital) claiming that he has been violent to women, and that DV was a huge part of their relationship, but he's not a scumbag 
And all the comments that follow are just as sickening. 'She'll go back to him. They always do'
And the comments after the women with her children who died. 'why take the children' 'how could they take the children' - what about the poor woman?
Are we so expendable?
And DV escalates. For anyone who's been there. It doesn't start off with a beating to death on the first date. It creeps in. Bit by bit. Until you're so low with self esteem, so controlled by finances, so controlled by emotional abuse, that when the physical behaviour starts, you just don't have the strength. Or you have children, and you stay for them.
People have no idea. No idea at all (well, a lot of people on MN do get it sadly, as we've been there).
