hmmmm you'd definitely know if u've moved on already when u can face him without hesitation, talk to him and won't care if you see him with another girl ... but falling in love doesn't exactly mean u were able to get over him already, know why? because sometimes or there would be instances when u are able to compare, find something in ur current guy that only ur ex has ... moving on takes some time ... and for me, the best thing to do is do the ordinary things u weren't able to do before, hang-out with ur girlfriends, read the book u weren't able to finish because u were to engrossed to spend time with him before ...
