There's just too much detail to my story, so here's the condensed version:

I've been with my girlfriend for about 3.5 years. She has betrayed my trust and lied to me on many accounts. "Technically" she hasn't cheated, but it's a very fine line when you have another guy live at my house with you while I'm away and sleep with him for a month... There's really so much stuff she has done that hurts so bad and is hard to let go, like doing things with two of my closest friends (who I am no longer friends with because of that).

I can't say that I'm innocent. About two years ago, while on tour, I thought that sleeping with random groupies would make me happy. BUT! I told my ex (at the time) that I wanted to do this to cure my depression. I never kept ANYTHING from her because I cared about her feelings as well. I gave her an out, but she said she was fine with me doing it because she knows that I will never see them again.

All the stuff that she has done, I had to find out by probing her with the SAME questions until her web of lies would slip.

Anyway, about 6 months ago, she left me for about 2 months, did a bunch of things that hurt me, got lonely, came back, wanted to make us work, and then I found out ALL OF THE LIES in like a week.

Ugh, can you believe this is the short version? So today has been 3 days since I broke up with her because I haven't really gone a day without these negative thoughts clouding my mind. It's been really messing with my happiness, so I had to take a break. She doesn't know that I broke up with her to see if she goes back to snorting coke, being with anyone who gives her a bit of attention, and breaks her 1 year sobriety goal.

So what I need help on is:
How do I let that stuff go? I can tell she's ready to put all of that behind her, but I didn't even know she was capable of it. It's hard to trust her again because she broke my trust while knowing that is LITERALLY ALL that I have asked of and given from day one. How do I delete the images of other guys being with her while we have sex? Should I just move on? She finally seems to be coming around and being more honest which seems to be so rare to find these days.

Thanks for taking the time to read my story. I appreciate what you guys do here.
