Me and my ex has went together 3 times since my freshman year. Now everytime i get a new boyfriend he gets jealous, and when he gets a girlfriend, i get jealous. I really care about him but i dont think he really knows how i feel, i've told him many time b4 how i felt, and it seems as if he's scared to be commited. Everytime we see each other, its like love at first sight then we might give each other a little kiss and a hug, then go our seperate ways. Now we dotn really talk but i really cant get over him, because any guy i get with, no matter how fine or how nice he is, i still think about my ex. What do I do?
