Punishing myself by not moving on?

I buddy, look into the 5 stages of grieving. It outlines how someone reacts to a loss in there life. I'm going through the same kind of feelings towards my ex and it's been a month and a half. Just check that out in google "5 stages of grief" A friend showed me that and it made a bit more sense on how I was dealing with the breakup. It hurts a lot when you love someone but eventually you'll get through it!
