to get revenge or not

[jilo]

ive been with this girl for over six years now, living together for 5, she is 5 years younger than me. our relationship was never great, but has deteriorated for a while and i see it being due to me not being fully interested in her for a long time, getting depressed about it and her losing confidence or respect in me because of it. the girl was never really that interesting to me in that, all we really did was have sex, smoke and hang out. it was never really the relationship that i wanted, i always wanted someone smarter that i could actually share life with, instead of just being there. i clould never really havein depth conversations with her at all. lots of my friends agree that she is an incompitent fuck. well, after 6 years of trying to get this girl to growup and act like an adult, id been getting completely sick of her and her shit, always being messy, not taking responsibility in her life, doing drugs n shit, plenty of stuff.
recently she had started blowing me off, and i knewit was because she was cheating. i called her out on it, but being the weak hearted individual that she is, she completly denied it. i moved out and started getting my life on track. she on the other hand is living with a cokehead drunk that she was cheating on me with, in our old apartment. i tried giving her a second chance and stupidly beleiving her lies. i am or was too insecure to beleive my own instincts about things. i put stuff aside feelings i shouldnt have. she told me nothing happened, that they were friends and her friends just kept her away from me and made the situation worse, and like a fool i started to beleive it.
so for the past two weeks weve been talking about taking it slow and trying to get back together. she has been talking about the slow part alot more than i have though, i let myself get sucked in and hurt and addicted to her. i told her all of this, and she seems to feel bad, she crys and sometimes i beleive her.
ive been beleiving her way too much actually and hurting myself bad from it.
yesterday i found out that a week ago, when we had plans to go out dancing she had blown me off and said her phone was dead. she was actually out with the douchebag kid shes now with.
now that i have further proof of her being a complete and total whore, im wondering what i should do. she dosent know that i fully know. we had plans today to go out, spend the day have fun, get a hotel room and fuck all night.
what id like to do, is absolutley fuck her rotten tonight bust her snatch up real good, and then right as im done tell her i know everything and kick her ass out the hotel room and tell her never to even think of me again.

on the other hand, the kid is going to jail in like a month, and im thinking that if i dont come out with what i know and tell her off, just play her instead of her playing me, wait till shes lonley and wants me (which i absolutley know she does) and fuck her a few times maybe drag her heart through some bs, cheat in front of her, shit like that. when i tell her i dont want her and she can never have me, she freaks out and crys like crazy, so i know she still has something in there for me, however small and stupid it is.

either which way, no matter what i do, since i always felt that she was bad and i protectd myself, shes getting evicted from our old apartment which i never signed the lease to, owes a 1000$ electrical bill in her name, and best of all, I BOUGHT HER 240 VERT SHELL FOR 300 BUCKS! we had gotten a 240 and put my gt30 sr into it and had plans for it to be "our" car. well she needed money and now its mine!!

sorry for the rant but its been a stressful situation. hit me up with some clear headed knowledge.
