It's a shame that all break ups can't have the loose ends wrapped up in pretty paper and big bow. It Sucks ... I am so sorry that you have been hurt this way.

There is probably numerous reasons why he decided to be a coward basically and an assshat.

Life is about lessons... Seems the best lessons I have learned has come from a shyt relationship. I found out what I wanted in a relationship and what I flat out would not deal with.

As already said ... Grieve the lose of the relationship. You could have really dodged a bullet with this guy, I know hard to see that angle of this at the moment.

Be kind to yourself, Try to remind yourself he is the one that has done all the harm and broken your trust in him. Don't allow yourself to fall down the rabbit hole of feeling its your fault... he has done this. If need be find a therapist to help you work through all of this.
