i've never married before so i don't know how it feels to get divorced. It must be break up x 100. You can read all the advices, but in the end you have to sit down and think about all this crap in your head which is probably just gonna make you sad. We all been through the stage where your girl hates your friends and you kind of keep distance from them, but if they are you're real friends they will accept you back if you apologize to them. Don't have any real good advice, but i hope you feel better and try and go out more like she is. Go out to parties, bar, vacation, so you can try and stop thinking about her which is the best thing to do i think. Goodluck.
