I was in a relationship for 4 yrs or so. I was deeply in love and never thought such a situation will ever come. I started losing my feelings for him and finally had to break up with him. It was hard for him. Took him 2 yrs to get over and still going. Now I like another person so much that I can't stay away. But staying close doesn't help so much either. I can't completely have feelings for him either. I tried being in relation with him and failed to show love or completely feel his love. Why?
