<human>: So in the back of my mind, there was always this thought. "What if she cheats on me", and I'd swat it away with a "naa you're being silly". Always this irking feeling though (ever since she was having sexual conversations with 3 guys while in a relationship with me, which she profusely apologised for and I forgave), that she would cheat on me.

So she goes out to the modern equivalent of a school disco, with alcohol and whathaveyou (drinking is not the main topic here), and she gets drunk. I mean hammered, with her friends. She kisses this one guy a lot, then moves onto her long-term friend, who states that the "damage had already been done, why not keep going?".

She phoned me this morning to tell me she'd cheated on me and I was really unsure of what to do, 3 years of routine and love and first times, it's a lot, you know? So she's saying "you shouldn't forgive me" la-de-da, and I take a long think about it.

I come back to her, later on in the same day, thinking that if we were to work it out, and overlook this one mishap then we could continue our relationship in the loving fashion I had come to expect. She keeps telling me that it wouldn't work, that it's too late etc.

Something seems wrong about her, so I ask and she says it would only hurt me. She tells me that the one guy (the long term friend) she cheated on me with has invited her around his house today, just her and him and they plan on being friends with benefits. She's around there now, and I'm struggling not to text her or call her, really badly. We used to phone every night for like half an hour and now I feel like we have nothing. I really loved and adored her. I feel like that meant nothing to her, but she said she loved me?

I don't know how to feel. I don't know how to react. I don't know how I *should* react. How should I get over her?
