TITLE: My[M22] ex girl friend[F21] and I broke up after 4 years. Not sure what to do with social events and mutual friends
POST: So some background info. This is my first relationship and we were going out for 4 years before breaking up. We met in college in a small program and over the years have made several mutual friends, that are in the same program as the both of us.

Now from reading up on r/relationships I know the first thing to do is cut all contact. But how do I go about doing this when it's likely that I will be seeing her at parties and other events. Should I just not go to events where I think she'll be? Most if not all our friends are good mutual friends so this is a tough situation for me.

Other than this what should I be doing? Currently I'm just sitting around at home, watching Netflix or hanging out with friends once in a while. I'm not sure how to get over this break up, as i feel like i won't find someone like her again. Any advice would be appreciated. Thanks everyone.
