what would u do if you found out that your bf/gf cheats on you? Options

[Spec_R]

Well long story short.. I've dated my girlfriend since December. We've been happily together although she lives 8 hours away from me. I visited her once and she visited me once as well. We met online on myspace. First time she meet me she flirts and then as we talked I started to like her. She's like those girls from Abercrombie or whatever you want to called it who flirts and so. But now I love her and she says she loves me too. But somehow I don't trust her so I'm testing her out.

She have a facebook and I faked someone's identity who doesn't know her but then try to get her attention. I stole someone else's picture who looks pretty hot in her eyes because she kept on saying that I have the cutest smile and handsome in the fake picture. As no surprising to me, she flirted with this guy who I stole identity from. I asked her if she's seeing anyone and she replied "no the last time i checked i think i'm still lonelyyyy". My heart felt so heart broken.

Later I asked if I could go into her myspace and then she said sure here's the password and so on. Then later I tested to see if she would let me go into her facebook. Then she said no, why? I was like oh, i'm just curious. Then she said fine u want my phone bill statment of who I call and calls me. Also my credit card & pin numbers? I was like no, i'm just wanting to see what your doing in there. (as you can tell I didn't add her yet to my facebook) Of course she don't want me to go in there to see her flirting with that guy who I faked. She said that my curiosity is starting to annoyed her. I should learn to trust her and respect her. If she feel like she don't want to give me something respect it and stop asking about it. But inside of my head I was like "yeah, I do but look what you did behind my back."

I don't know what to do you guys, I mean I am in love with her but it seems like all she wants to do is have fun and flirts around. If she loves me and respect me then why is she doing this right? Should I continue on faking and see where it leads me to. Or just f**k it and tell her straight up.... but how???

She say she loves me and all but now she's doing this behind my back???
