TITLE: How soon is too soon to move on after a break up? And how do I start making new friends
POST: I [26M] was in a 3+ year relationship with my ex [23F] and we broke up less than a month ago. We had a LDR for the past 2 years because she moved back with her parents in Dubai and I don't have the experience to get a job out there atm.  I found out this morning that when she told me she was out with her parents and couldn't skype me, she was actually out on a date and I have a feeling she didn't go home. Is it normal for someone to move on this soon? Also, do I do the same and forget about the past 3 years and just jump back into dating? Whilst dating I lost touch with any other friends I had, so she was literally my only friend.  What's the best way to gain new friendships?
TL;DR: 
after a 3 years relationship, should I just forget about her and move on? And how do I go about making new friends
