How/why did your last relationship end?

He cheated on me once, told me a few months later. I forgave him. He was supposed to visit me for a weekend (490 miles distance), we fought and I told him to cancel because I needed a break from fighting for a while. He didn't come, instead he broke up with me because "you just don't want to break up with me, so I'm doing that for you". (wtf? no I don't?) We reconnected, he had severe depression, was on meds, din't go to work, was cancelling appointments with a therapist his boss ordered him to go to, (out of concern, but also he could get a doctors note so he wouldn't loose his job) feeling guilty, we were both miserable. Then one night we were skyping. He quit me again (guess the first time didn't count?) and asking if I'm seeing someone else. I wasn't, I was too madly in love with him.

Then he told me he is seeing a girl for 2 weeks, he needed someone to talk to, but that it was nothing serious (seriously?!) I wrote him a very lengthy email, explaining my feelings for him, describing how we first met, telling about the vision I had for our future and how I couldn't imagine him to be being such a good liar that he faked feelings for me (I knew something was up when he cheated on me, he is a reeeally bad liar) and also about the struggles we just had those few weeks, always fighting, exchanging the same bullshit over and over again. That I thought it was worth trying to save that relationship but that I need his help to do so. He called me an hour later, telling me goodbye. Only 30 minutes later his mom (who I have called, at 6 in the morning, not speaking my mother tongue, really stressed and mad at him I had to deal with that bullshit too) drove him to the hospital where they pumped his stomach.

 He moved back in with his parents. I was on the phone with his mom for hours, because she needed to understand how it came to this. I talked to his friends, his colleagues, his father, his sister... He did rarely say a word to me. Except that he didn't deserve that I called his parents and I didn't deserve him hurting and upsetting me again. He then told me he won't be online for the weekend, because he is going out with his new girlfriend. 



 Now the worst part. We are not teenagers. We are both in our late twenties, there were plans to move in together, to marry to make the visa process easier. I also didn't fall for a long distance pseudo relationship. We saw each other just about 7 days a month. I had flexible work and we had our shared travel money, that I would use to fly to him as often as possible. Only 4 weeks before the affair came out, he ate dinner with my grandmother my whole family *(who all in the beginning thought long distance relationships could never work)* and me, after that dinner they all started giving wedding advice, talk about grandchildren etc. This wasn't me being completely delusional, this was a guy going back to the hardest episodes of puberty at nearly 30 years. 

 There is much, much, much more to that story. But that's the essentials. My relationship didn't end, it blew up like a funking H-bomb.
