The ex is from 5 years ago and currently has a partner. I'm still very much in love with him and we never ended on bad terms or anything. We talk occasionally but he has a gf of a year so you know, obviously we are not a item. 


But recently tried to get back in the dating scene and was told I can't date anyone because I still love my ex from five years ago. 


Is this true? Should you not date anyone if you still love a ex? If it's been five years then when will I stop loving him? Does that mean if I don't stop then I can never date someone new?
