So I'll try and keep this simple. I can't resist my ex (A). She's absolutely adorable--all her mannerisms seemed to be engineered to elicit affection. Not a good thing, or a bad thing, merely an observation. Recently, I've been looking into this other girl (B) , and I've finally worn down her resistance, much like a hunting cat which has chased a gazelle until it would rather be devoured than keep running. Amonst others, the three of us were at a party, and i spent more time with B than anyone else. However, i had to leave, and A caught a ride with my ride and she lures me back to her house with beer, uses her infernal demon magic, etc. Of course, one thing leads to another, we fuck. Here's the dilemma: she's bad news, she fucks with my head (no fault of her own-that's my own hangup), and I want to get with B. But A is irresistible.

Totse, how do I resist her?

I'm sure that the majority of Totseans will tell you to simply fuck both, especially if neither has a problem with you (or knows that you are) fucking the other one. Your story wasn't quite long enough to elicit those sort of details, but from what it seems, one is not proving an impediment for the other. So enjoy them both.

Or, if you don't actually like your ex (because she fucks with your head), and simply want to be rid of her, just refuse to spend time with her. Begin dating B and remind youself to remain faithful in the face of A; remind yourself of all of the ways that A has manipulated you in the past and why you broke up with A in the first place. The same applies if you posess moral scruples (which would be rather shocking): don't hang around with the Succubus and you may yet keep your soul.

Tazer the bitch.

Failing that,
look at everything she does, the whole way she acts. Break it down in your head, see how it's just a pathetic facade and how her acting is really rather shit, because if it was good you wouldn't even know it was going on.

Look at how pathetic she is and look at how she's just the same as all the other girls, just nastier. Not necessarily a bad thing, but she's definatly not any better but as a liar.

Then go find a real person and fuck them, it's much better, trust me.

Mor details, i guess: I was with my ex on and off for the past year or so, basically whenever we break up we end up back together eventually. I did really love her, and probably still do. She never hurt me intentionally. As for the other girl, she's just a really cool crazy bitch with good taste in music (a must).

You weren't cockblocked, you simply gave into a temptation.

What should you do?

Not give into temptation.

Well I know I wasn't really cockblocked. Perhaps I am over-dramatizing this. The guy with a name I can't spell made a good point, though.
