ok bro, i see a problem, now, if you ever want to get married and actually have a life, you've got to assume that you'll find a girl that you can actually get along with (not this chick obviously). When you think of a relationship as a big argument then you'll never find anyone. I guarentee there is someone whom you will hardly ever fight with, they're out there, you just gotta look.
and as for this bitch, just do her and move on, nobody will care if you've done it with her or not, infact, it makes you more desirable to women...
