<human>: Summarize the given text in a few sentences.

Long story short, we were together for a little over 2 years and she broke up with me after she went to college and we decided that long distance makes us fight more and she said she felt she was "missing out" on college. We didn't go strict no contact, and also made the mistake of getting back together over winter break. We've sort of been sporadically texting (checking in and whatever) since we've both gone back to our respective schools.

Anyways, she's drunk texted me a couple times lately (saying things like "I still love you" and stuff), and last night it happened again with 2 guys taking her phone from her and drunkenly calling me (knowing I'm her ex). I called her today to talk about how I don't like that and if it's going to keep happening, then we should just go strict no contact. She then revealed to me that she had slept with someone (previously we had only been with each other).

Now I'm just reverting back to the beginning. I haven't even kissed anyone since we've been apart, and to know she's already slept with someone is just crushing. I had made progress in getting over her, but that's all gone. I'm just back to missing her so much and can't stop thinking of her with other guys nows. I don't know what to do. It's all I can think about. Aside from no contact I just don't know what to do. I know the relationship isn't just about the sex so it shouldn't matter that she was with someone, but it does and it makes me hate her. It makes me feel like I wasn't important at all....I don't know I'm just sort of rambling now.

What do I do?
<bot>: Ex-GF of 2 years told me that she slept with someone and it completely restarted the healing process for me.
