I was in this situation..I was on and off with a guy for years...inbetween (most of the time) we still talked, acted as friends...but it hurt, it hurt everytime I saw him with someone new, he talked about his new relationship, etc. I begged God time and time again to let me finally get over him...it took a long time, but I finally did. I think part of the reason it took so long was that I had an unrealistic view of him. I ignored or quickly got over the bad and held onto this fantasy view of him. Finally I realized the fantasy I had in my head that was him and the real him were far from the same. For me TIME is the biggest factor in getting over someone, time has to pass...and it varies depending on how much you like/love them...and the other factor is, seeing things in a realistic light...love seems to cloud your vision, at least for awhile, especially in the beginnings of a relationship...try to see it all as realistically as you can, be brave, be strong, allow yourself time to heal, and you will get through this.
