I read my gf's blog and found out she is thinking about dumping me & she is looking at other guys?

We've been together for almost two years... when i read it it killed me.. i'm basically scarred for life she described every guy in detail and said how hot she was.. and like one guy had a gf and she talked about how she was pissed off when she found out... should i take revenge on her and dump her before she does it to me? i swear i loved her with all my heart i just want to do something before this pain kills me.. she hasnt cheated or anything and she said she still cares about me in her blog.... what should I do?
