(I know the term is becoming obsolete now).
We've split up now. She split up with me.
I am just interested.
She told me that she left me because she knows I deserve love, and she can't give it. In her words she 'Couldn't love anyone-she couldn't even love her own children'.
She tried to kill me once (I think) violently. She has said she'd disappointed with this, she thought she'd get more of a psychological thrill or high, than she did once she'd done it.
Those two instances-but other things are less monumental. E.G I once arranged a bit of an evening out for her and one of her children and she didn't fancy it. Her son really did, so I said 'come on, won't be for long I'll just get us some dinner, couple of drinks then home'. She said okay, and then said to me 'Remember, I didn't want to go'. She then caused a major upset that night, really upsetting her child (and me).
There are several things like that.
