*~*A Heart Seeking Healing!!!*~*

Okay, Im in a tight bind so imma need anybody and everybody to help me out with this one. I have known this boy S for about 4 years now. we went out on and off for about a year. At the present moment we are off. But i am decidin' if i should move on or stay with him. Let's start from the begining. I started talking to him a few days after i ended this kinda serious relationship. he had just gotten out of a serious relationship himself , so we kinda leaned on each other for support. Wel one thing lead to another and we ended up going out with each other. But soon after he stopped callin me and breakin promises. There would be times where i didn't hear from him for weeks, but he never did this to his past girlfriends and he claims that he can't stand them. so i let him go. Then about Jan. we picked back up but he had started his new job so we didn't have time for each other really. then in Valentines' Day, he didn't even call me and the next day he say me and he didn't even say hi or try to recognize the fact that i was livin!! I let him go but he begged me to take him back. Then in March, my birthday, he didn't tell me Happy Birthday or call me. so instead of leavin him i just stop makin an effort. we ended up breakin up silently. we havent been together since, but we still talk. May rolls around and its prom season. I asked him if he had a date and he said he had to choose between two people, his X-girlfriend, and a girl he really didn't want to go with. so i put i out there that i didn't have a date or anything and he said he wanted to go with me, but he still couldn't choose. Of course i was heated, but i waited to see if he would choose me. HE DIDN'T!!! he went with his ex!! The one he said he couldn't stand!! I have grown to love him but when i think about all the wrong he has done to me, i get kinda depressed, not to metion how much my self-esteem has lowered thinkin the reason why he didn't do this or didn't do that was because of me. wat should i do?
