In honor of the Ides of March, what was a time you were stabbed in the back by your closest friends?

About a year ago I got dumped by a girl who I truly loved with all my heart. I now know the relationship was going south but back then I would have done anything to make it work. So she breaks up with me, we say that we'll stay friends blah blah blah. I got very depressed after that and she was always the person I went to for comfort but it wasn't the same as when we were going out. She felt distant and the more time I spent with her the more upset I ended up becoming. While we were going out I managed to get her a job working with me at a fashion company so we were next to each other 7 hours a day at least. Not really healthy for either of us but she needed the money.

The only other person I truly trusted was my best friend who lived across the country. I would call him up and talk about shit unrelated to my situation and it was refreshing, even though I knew the moment I got off the phone it was back to reality. I knew my best friend for 11 years and had stayed with him a year prior. He wanted to come live with me for a while until he could find an apartment. So he came to live with me about a month after I got dumped. I set him up a bed, got him a job and all that good stuff. I was still in a really shitty place mentally and would contemplate suicide on a regular basis but I tried to stay chipper around my best friend and ex the best I could given the circumstances. My friend would try and cheer me up but I was so far gone and in my own head that any attempt at trying to make me fell better was met with apathy.

Exactly a month and a half later I find out they're dating behind my back and didn't tell me because they knew it would hurt me. I felt such a huge flood of emotions and had no way or person that I trusted enough to vent too. So I did what any depressed emotional idiot would do. I yelled and cursed them both out and cut contact with both of them for about 3 months. Some of the things I said were brutal and were totally uncalled for. I felt so betrayed and taken advantage of that just the thought of them would ruin my day. I tried to get back in contact with them but I can sense they both have moved on and don't really want to rebuild our friendship.

TLDR; got my heart broken by a girl. best friend of 11 years dates girl behind my back. I yell at both of them and loss them both.
