<human>: So I've been dating this girl for almost 2  months. Everything has been going well until we had sex last night. It was my first time, so it made things a bit awkward, but nonetheless it was awesome. 

After this, she tells me I'm the only "nice" guy, she's ever dated and that she mostly dates "assholes". This really made me cringe because I hate being the nice guy. I'm not a nice guy! I think I may have been playing up the niceness and playfulness during most of our dates just to build up attraction, but I haven't really shown her my serious side. When I asked her if she wanted to be exclusive, she gave me this long rant about how she's a commitaphobe and doesn't want to get into any relationship that might not work and thus waste her time.

To me, we have a lot of chemistry; we share the same values, think the same way, and share the same sense of humor. We have different hobbies, she's outdoorsy and I'm more nerdy. I know our opposites have attracted each other. We make each other laugh and smile, but we haven't had many serious conversations. So I think the crux of my situation isn't that we aren't compatible, but that we haven't shown each other our more serious sides. I told her to give me one more date to prove that I'm not this nice guy she thinks I am. So is this irreparable or just some sort of mind game/test I need to get through?

Could you distill the essence of the text into 1-3 sentences?
<bot>: dating a girl for <2 months, doesn't want to commit as I'm too nice of a guy. I call bullshit!
