Getting Back With an Ex

OK, I'll make this post as concise as possible without leaving any important details out. A little less than two months ago, I decided I wanted to take a break from my girlfriend of two and a half years. I was really depressed and confused - thanks, at least in part, to working almost 70 hours a week at two jobs I hated - and I needed time to clear my head and figure out what was going on in my life. My girlfriend obvious took this very hard. She basically stayed in her room for a week straight, doing little more than crying her eyes out. She ended up losing twenty pounds. We talked a little during this period, but every time she texted me I would keep my response brief because I needed to spend some time alone. We were suppose to go to a wedding about a week after a break-up, but I ended up telling her I didn't want to go because I was worried that we were going to fight and embarrass one another. Needless to say, I fucked up in a lot of ways. About two weeks after the split, I started a new job and began to feel much happier and more clear headed. I decided that I wanted to try and get back with her. So I ended up buying tickets to Passion Pit, one of her favorite bands, and things went well - I held her hand, rubbed her back, and we were generally flirty together. But a few days later she told me she had had sex with another guy. A drunken hook-up. This hurt like hell, of course, but I couldn't get mad because she was single and didn't do anything wrong. Feeling like I was going to lose her for good, I did everything in my power to get her back. I left her flowers, candy, cards, letters, etc. every day for a month and a half straight. I texted her every other day letting her know how much I loved her and wanted to make things right again. She ignored me for the majority of this period, save for an occasional "thank you" or brief text message convo. Until last Saturday, when she agreed to go out for a drink together at Plaza Azteca. We had a good time, ended up going grocery shopping together and spending the night with one another. I made dinner for her, cleaned her house, rubbed her back and feet blah blah blah, basically everything I could do to let her know that I wanted to turn over a new leaf and to show her that I was worthy of another shot. We were interacting like boyfriend and girlfriend, there was no mistaking it. But after I left the next day, she completed ignored my texts for a day and a half. When I finally talked to her, she said that Saturday didn't mean she wanted to get back together and that we "shouldn't rush into anything." And then she told me that she'd had sex with the same drunken hook-up two more times. Ouch. So I gave her an ultimatum: I told her if she wanted to be with this guy that she should go for it and cut me loose so I could move on, but if she still thought we had a chance that she needed to cut this guy out of her life and take me out of limbo. She said she didn't know what she wanted to do, and that she missed me a lot and that she still thought we had a chance, but that she wasn't sure if she could forgive me for hurting her. She claims she has no intention of dating this guy and that he's basically just a friend with benefits who was there for after when we first broke up. I'm willing to forget about her sleeping with another guy if she's willing to forget about all the things I did to her in the past and rededicate herself to me entirely. So what do I make of this? Do you guys think this relationship is salvageable? How long should I let her be indecisive before finally just saying "It's over, I need to move on? Thanks, Mike
