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

I found out my girlfriend was cheating on me while she, I, and several friends were on a spring break roadtrip. It caused a lot of awkwardness, but I broke it off with her and she moved out. She seemed so genuinely broken up over it and spent the whole time crying her eyes out  that I let her go in the gentlest, friendliest way I could. By the time we got back from the roadtrip, I was less angry and more sad so there wasn't any yelling or screaming, but a sad letting go.

I went no contact like I knew I should. Deleted our pictures I couldn't look at, blocked her on fb, haven't responded to her multiple texts/calls/emails. It has only been a week, but I feel like I'm already about to break the no contact so I'm writing here instead.

The more I think about it, the more sure I get that she's still seeing the guy. She told me she wasn't when I broke up, but the way she said it makes me think it's a lie. I know it's not my business anymore, but it's just a big "fuck you" to our three years together. It's really eating me up inside no knowing for sure. I feel like if I knew, it would help me move on.

I am about to graduate college. I am broke from spending my meager savings doing stuff with her (huge lesson learned), I didn't get into grad programs I wanted to go to, I have barely slept, I can't focus in class, and frankly I've been drunk most of this week. I had wholeheartedly planned on proposing once I was financially stable. I feel like I've lost everything.

I've come one click of the "send" button away from messaging both her and her close friend who she confides in. I know I shouldn't.
<bot>: Found out girlfriend of 3 years was cheating. Broke up. Not knowing if she's still seeing the guy is eating me up. I feel like I've lost everything. Help me not contact her or her friend.
