This guy used to be my college mate (now he is in his early 30s and me in late 20s). After college we stayed in touch and recently after a meet up we became quite close and the frequency of interaction increased (we both stay in different countries). Initially he expressed his interest in me, but i declined (coz things moved on too fast). With time, when i came to know him better, i developed feelings for him and now he declined my advances. During once such meetings he confessed his love for me, but wasn't ready for a committed relationship and wants to concentrate completely on his career(which didn’t make any sense to me). I decided to back out and move ahead but he won't let me do that either (somehow he will try to get back in touch)...In the end he wants to be in touch but not committed. i have no issues being frndz with him. When i pull back he will get all romantic and playful. If i reply back he gets defensive. His hot and cold treatment drives me crazy at times. guys i am asking what sud i do here.
