Yeah but Carl mate, she self harmed to cope with me... it was intrinsically linked. I was the the cause, without doubt.
What separates her having done it, and me taking a blade to her arm?
Not much in reality, i was still the cause and reason.
Hmmm
Self harming is way more complex than that.
I've know lots of kids who self harm, it's never been a single trigger. Never "he did x, so I self harmed".
Kids can tell people it is, they may even believe it, but it never is.
It's a much much more complex mixture of emotions than that.
I might suggest that you and she may have similar personalities and you drink to cope with life's pressures but she self harms. That's just a guess though.
Blame won't help the situation one iota though.
