Bro, been through a similiar situation just like yours, I was so possesive with my gf before that all of a sudden she just broke up with me a month after I committed myself totally to her...the twist in my story is there was another guy that was taking over and giving her all the freedom, i banged my head on the bed post the day that she officially broke up with me, i cut my forehead and i had to get it stitched up, that very same afternoon, she went home with the guy, to my stupidity, i kept on asking her to give me another chance for 2 more weeks after the incident, with her just totally ignoring me, turned out a week later it was her bestfriend that i was texting for comfort, she got angry, ended up fighting with her own bestfriend because of me, and then it came to a point where she was the one asking me to come back, fast forward 3 1/2 years, here I am, me and my gf now(my ex-gf's bestfriend) are excited to have our first baby this july, she's somewhere in manila, still sending emails to me asking me to come back to her. The point of this bro is, during the time after the incident, i tried to kill myself, 2 attempted suicides, good thing i did not succeed, and here I am right now, happy, contented, excited to finally have my own family. There's no point of ending your life, let me quote from Semisonic: somehow, every new beginning comes from some other beginning's end.
I'm a loner pod bro, hopeless romantic...hope all would go well with your situation right now bro....it takes time to heal jud....
