Hey guys me [20m] and my girlfriend [20f] of 2 years just broke up a week ago to work on our own issues. We've been fighting for a long time and she decided she was done. It was so hard the first couple of days. I loved this girl, she was my best friend. We did everything together and I lost all of my other friends while I was with her. Now Im trying to move on by dating other girls but none of them compare to her, she just seemed so right for me other than the arguments. What can I do to get past this and start enjoying other women? I've always had the mindset that love isn't a real thing for guys and we just get attached to the routine but She changed it for me. I was willing to look past the fighting because I just wanted to be with her.

Tl;dr Girlfriend broke up with me, how can I get over wanting her back and start enjoying qualities in new girls?

Edit: Thanks for the responses, it's great knowing that there's a community of supportive people who have my back.
