Re:
Having been there, it depends.
Why will you be seeing her again?
Personally, if *I* do not want to see her, or might act, and by I mean acting a way that MIGHT get certain results, I wouldn't even bother with the interaction.
Once an X, always an X. And with that mind set, treat her like new acquaintance. Do not try to get her respect. You do not need, nor want it. The value of the respect you receive is in direct relation to her own respect and value. A valueless and dispresectful person is not worth trying to gain the respect of. Moreover, you don't CONSCIOUSLY do anything to gain respect, because then you're only acting 1 way to get someone's approval. Then you have to figure out what to do for the next person to get their respect. Like being a puppett?
Fact is, I've run into X's before. IT ALWAYS pays to be the bigger person, so that at SOME POINT, they realize how awful they truly are. And it's ALWAYS worked for me. Some guys like to be d!cks, but they end grovelling, or feeling bad years later, or maybe just months later. For some reason they feel BIGGER, but it only makes their EGOs bigger. This only justifies her SH!TTY behavior MORE, and will further prove that it's OK to be a CVNT.
Every girl thate ever dissed me or dumped me or basically just flaked, came back because I believe in being the good person in all situations. It does not pay in the long or short run. In the short run, you feel crappy about 5 minutes later, and in the long run you do not get the benefit of the doubt. I've been able to redate girls who flaked, or talked ish to me, for no reason, years later, or keep a network of FWB's, just because of that. Not to mention, BEING BIGGER requires no FORETHOUGHT, no planning, no worry. Nothing.
During college, my X was a year younger, we'd broken up, but she REALLY didn't want to be, SHE just wanted to give me the pain in return I'd given her for why we'd broken up. THE MINUTE I began dating, or acting OK with things, it really bugged her, because her negative actions NO LONGER worked.
My LDR to Texas (who may have cheated on me, I certainly dated other girls), ended it right after my Hawaiian trip. About 8 months later, I went to TX for business again and she was there, fully expecting to get laid, I went **** and funny on her, got bombed, and wound up realizing she went total douche on me. Nothing happened, she was miserable. Only until months later did she apologize and realize how she messed it up. And maybe she'd find another guy soon, nonetheless, it just pays to be the bigger person at all times. Thereby keeping your reputation POSITIVE.
