I had the same problem. I felt like this person was the one and i wasn't going to let them go. after we broke up i kept asking him out and he was really nice about letting me down easy. I met someone else and fell in love real love with him and got married after years of dating. I keep in contact with him because him and his mother helped me through ups and downs in my life and I now consider him a really good friend.
That's not loving. That is possessing and controlling. I f u love someone, let them fly free.I f they love u, they will come back.
tell them those exact words! dont be afraid!
