The problem is, He used to be a very good friend. The thing is, he's trying harder and harder to try and indoctrinate me that WE BELONG TOGETHER.
I've had people pull similar shit on my girlfriend. It's nothing a few kidney punches can't solve.
And I'd say you're making the right move with telling him to leave you alone for a bit. If nothing else, it gives you some breathing room, and at best it means he'll realise he's being a twat and stop pulling his Bible-bashing bullshit.
