Kaveman i see this situation arise with alot of my ex girlfriends, vindictive, spiteful, jealous, controllive, hated me tripping but would gladly get pissed and cause me a horrible night :/ i mean i think i have met one girl in my life that i got very close too, n she still fucked me over, i think i always choose the wrong type of girls, and then when i do choose the right type of lass, she isn't for me, i feel i have wasted almost 9 years with 3 seperate women, and one has come close too love, i feel similar traits to your situation right not, my gf is only 21, very much is making it obvious she doesnt want to be with me though, denies all knowledge it yet shows no effort, this girl i have been dating over a year and i still dont know her, i am yet to find the right type of girl for me and im 25, broke, haave an etizolam habit, addicted to plo cash games :/, im a mess :/ ... cnt hit much lower!
But with that sense of feeling i cant hit much lower there is a middle ground, i feel like like the only way is up (as cliche as it might sound :/)
I definitely feel you should stop contacting her altogether, people like that can scar you in future relationships and most definitely have

..
Just a tip, dont go rushing into anything with anyone, take things easy, jumping in the sack didnt make me feel any better, nor did it boost my ego or self esteem (i hate one night stands though) some people like my mate, do that sort of thing , to get over a lass, i find it a silly path to take, but i understand everyone has different ways of "getting over someone"
There is always a thing that ended with my previous relationships that made me say "right im never going back there again" there is a line a certain limit u can get pushed too , so far, u fall out of love with them completely, and begin hating them, if u feel u want to talk some more im always around for a pm or chat

, much regards, bare_head
