hmm..imho,i think whoever the guy is(ts)..he's overreacting ...sometimes..some people just want the closest person to them to just be a support..not asking you to do this or that..but because when you do a lot more for the other human being..and the other human being just ignore it..you'll feel unsatisfied and slowly will make you feel angry and the result,ur here and she's out there feeling happy and maybe not even thinking of you. Sometimes..handling this such situation you shouldn give more than what you can afford..just be yourself..trying to be somebody else will just hurt you in the end.
At least..the decision is in your hand..some people are not that lucky where their future lies in somebody's else hand.
My only advise..put a stop and move on with your life
