Most Helpful Guy
I'm sorry to hear about this. sounds like he didn't really know how to treat you properly.
my advice is in the future that you have to take some things. You can't be completely passive in the relationship. If you like him show him. If you want to talk to him, call, text, etc. Try to take a stronger role in your relationships so that the guys you are with don't feel like they can just walk all over you. It will also demonstrate to the guy that you care and have interest.
but I am sorry to hear about his lame break up. that's pretty cowardly in my opinion to just fade out on someone
