Hey man, although I eventually ended up breaking up and getting back together with my girl, I know how that can feel. I'm sorry you had to go through with that, we've had our fair share of "rocky" relationships.

I hope you took the time to have a drunk day, food day, or whatever other vice day. Might not work for you, but a full weekend of unapologetically indulging yourself is not bad to kind of sit down and reach a thought about how you feel. Hope you are doing well.

Fuck that guy who told you to just move on. It doesn't work like that, and whatever complicated emotions you are feeling I encourage you to indulge and just feel comfortable with your individuality. Although people have broken up and been broken up with, everyone handles it different, grieve for yourself and what could have been and think about what you can do to move forward.
