I just graduated from high school, and i have a bad case of the itis. First time i ever started falling for a girl, and i got used like I was her f-ing tampon(never spending shit on another girl unless we're dating). Took her on really nice dates and all that shit, and on prom night i found out she's farkin another dude. I haven't been able to get any of this off my mind, and i've just been ignoring her, doing all the standard "get over her" stuff, hanging out with friends, just staying busy. But still she's all I can think about. Would it help to confront her about this shit? Its really fucked up my self esteem and given me some insecurities. If i did what should i say?
Thanks in advance for any and all replies.
