<human>: We were together for 3 years, she was my first... Everything.

She broke up with me a year ago, a fucking year ago. During the relationship she cheated on me twice, i stupidly stayed with her because she was honest with me about it and because i loved her and she said she was sorry. In the end she dumped me for another guy. Later i find out that she cheated for a third time during the relationship, this one she never told me about.

The jist of it is that she has the ugliest personality in a girl, what kind of girl cheats on a person multiple times while still being able to say 'i love you' to that persons face? 
She is the purest form of evil i have ever met, yet my mind can't accept this. I constantly think of her and the few good times we had.

It's been a year so why the fuck do i still feel like this? It's driving me nuts!

Can you provide a brief overview of the text?
<bot>: Ex-girlfriend is a snake who i still love for some fucked up reason, i can't figure out what the reason is!
