Who gives a fuck, what you say about him to other people is only going to make you seem like the bad guy (and really- what people behave like to each person depends on their interactions alone so it'd be selfish and vindictive too.) It's none of their business, and they'll find out in time and make their own decisions if he is a total ahole to them. Like everyone else has said move on. Cut contact and forget about it, not worth the drama dude. :/
And you don't really have grounds for legal action because you keep baiting his harassment by talking to him.
Given what I know of his capacity for mind games and his crossing certain personal boundaries, I feel a bit of a baser emotion regarding how others feel about him. I kinda thought 'should keep that dirty laundry away from sight' but I am a little upset at the idea that there are people who have not a clue as to how weird he behaved with me
I know a person or two like that. It's very, very frustrating when the rest of the world thinks the sun shines out of a person's ass and you're apparently the only one who has seen through their bullshit to the disgusting person they really are underneath the phony exterior.
He's someone who is perfectly fine with exposing others' flaws; should I get all retributive and do the same? Or just stick with cutting him and his immediate circle out and moving to a completely separate life? (am going overseas anyway)
The latter. I saw a quote the other day that said, "The best revenge is being perfectly happy and having a great life without them." Especially since you're moving overseas, so there's little opportunity for him to continue to screw with your life (a luxury I don't have in my own predicament, unfortunately).
Forget him and be happy overseas. If you're not happy, fake it. Unsubscribe to his statuses on Facebook but don't remove him as a friend, so that you don't have to be reminded of his bullshit but he can see how happy you are without him.
oh i thought you defended the idea that women should be able to dress up in a sexy way that emphasizes their best physical qualities to attract men and that somehow had nothing to do with how the men should judge those womens personalities? why the sudden 180c turn?
