Search Results: girlfriend is losing interest

My girlfriend and I have been going out for about 3 and a half months now. We rarely get to hang out, I think we've gone out about half a dozen times since we've been dating. And it always seems like I have to try too hard to start conversations and keep them going. We used to talk for hours about anything and everything, now we rarely get passed talking about each others' days. I just feel like I like her a lot more than she likes me. I've also been told by a mutual friend who volunteers with her that she's EXTREMELY flirty with the other guys that she volunteers with, stuff like always trying to sit next to them, paying a lot of attention to them, putting her arms around them, going through their pockets, etc. I really don't want to lose her, I don't think I'd ever find someone quite like her. but if she is losing interest in me, it's not fair to me to stay with her. I just want to know what everyone else thinks. Thanks! (P.S: if you answer the poll, please also answer in the question and explain your answer)

I got this girl to trying 6 months, I have been playing hard to get her attention, now she is my girlfriend, but now I am losing interest in her. We never have had sex, I don't know why I am ignoring her, she text me, sometimes I reply, sometimes I don't. Sometimes she get mad due to my rude behavior, why I am doing like that?
