So I was with my girlfriend for a year and 4 months help please
After 14 months the day of the 10th our 14 month anniversary she had a new girlfriend which was a girl I ****ed before and use to be a good friend, and now they're together the day we broke up. When me and my girlfriend first broke up for a few weeks I was angry and mad and on a whiskey night had sex with the friend she fell in love I hurt her because I told her I loved my girlfriend and wanted to be with her and spend my forever with her pretty much. Now they're on the phone every night in arelationship on fb and etc has her friends texting me saying things happen for a reason and I've left them alone, and people saying let them be happy together I sent her a messaging saying I was sorry and I wish them both the best of luck and happiness because everyone deserves it. But my heart is torn into a million pieces I don't know what to do I smoke myself to sleep or have night mares etc... help. Advice?
