Suki is right. I felt in love with my first love too. I was never intimate with him, but I loved him anyway. My whole world revolved around him and I couldn't get him off my mind -- this went on for a LONG long time.
But he only came around when he broke up with other girls - or when he was cheating on his girlfriends.

He was just using me. He didn't really LOVE me. It seems that it's the same for you and this guy. He's just manipulating you, like Suki said.
Don't waste your life and time on this guy. I know you love him, but he doesn't feel the same - it's obvious. Let him go, and find someone who feels the SAME for you as YOU feel. You don't deserve this kind of treatment. God bless & take care. Hugs, Lee
