Loving the Same guy

I NEED SO MUCH HELP…please read this!!!

I have feeling for the same guy and I know they’re not going to change but I want to move on and stop having all the pain im having right now watching on the side lines while he has his girlfriend and his close friends I aint got no boyfriend and no good friends, I did when I was dating him though. I just want him back but how do I do that without hurting myself more than I already am? should I try to get him back or should I just walk away from this game and move on to another guy that makes me just as happy as this guy made me feel? when im around him I feel like im meant to be there and that he is really the right one for me. I had given up on love when I met him and then we started going out and I felt like he was the perfect guy for me now im just standing by and watching him smile and be happy. I may look happy for him which I am but it hurts so much to watch him be so happy.

I lost my virginity to him the second time we went out but the first time I really loved him and when he broke up with me for the first time I couldn’t sleep at night and I was depressed all the time, and when we started going out for the second time I just felt so happy and I never wanted to let him go but obviously not wanting to let go made him not want me anymore and so now hes going out with another girl and im all depressed again. I just want him to be the guy I spend the rest of my life with. the second time we were going out he told me he was going to give me a ring because he wanted to spend the rest of his life with me too. and I got so happy and I just got so prideful in the relationship we were having. after we broke up I went one day with feeling so depressed and the next I got him back but just as a really good friend I didn’t get him back as a boyfriend and now I just want him back I and love him so much and I just want to solve this. my heart and my mind are telling me to go for him, he treated me like I was so much better than he deserved and it made me feel like for once I had something I truly needed. but all that is gone and I just want it back.

How am I supposed to do that?

How do I get him to want me again?

How do I let him know I want him back without verbally telling him?

If I cant get him back how do I get rid of the pain building inside of my heart?

I know it a lot of questions but I really need help!
