Lol, ive been through the same thing.

Me and my ex were in an unhappy relationship, i fell out of love and my current partner who was also in an unhappy relationship at the time also fell out of love with her, and then we fell in love with eachother. We left those relationships behind and got together and its the best decision we couldve made. Initially there was a lot of pain involved for all people, however We have been very happily together for over 3 years, my ex has moved onto a happier and healthier relationship and my partners ex is still single but shes happy in doing so because she wasnt ready for a serious relationship anyway.

So thats an example of how even though everyone else here thinks your a "piece of shit", i think you're a human who is allowed to love who he wants and allowed to make mistakes if they turn out to be mistakes, if that also makes me a piece of shit for thinking that, thats fine. Like i say, life is too short. If i wasted any more years of my life where i was, and not having what i have now, i would never forgive myself.
