IT'S COMPLICATED!

A long time back, me and my friends were just hanging out and were talking about our dating lives. At that time I was single and my friends were just recommending some guys for me to date that they knew. So i just randomly decided to see how it goes and texted one of the guys. He responded very soon, and we started chatting. We mixed along very well and got to know each other. I started liking him but hadn't confessed it to him by then. But still we knew that we liked each other and everyone in our friend circle too shipped us everytime we were together. So we used to hang out a lot and everything went very well. Until one day, when one of my old close guy friends approched me and confessed that he liked me. At the first, i thought he was kidding and left it off as a joke between us. Even he didn't bother about it that time. But as soon he got or know or observed that, me and the other guy are getting pretty close, he again approached me asking if I like him back or not. I said no, because i didn't wanted to ruin our friendship by dating. But then he asked me whether i liked this new guy and i said i'm not sure but we're still seeing each other. I didn't wanted to take any decision untill i was not sure about my feelings. But then my old guy friend and i also started keeping in touch and used to talk everday. He became pretty serious about me and asked me on new year's eve whether i will give him a chance or not(for dating).. nd i got confused because i'd never seen any guy this serious to be with me. So i asked him to give me some time to think. After a lot of thinking, i said sorry to him and said no we can't date to my old friend. But i don't know what happened to me, everytime i used to face him, my feelings would just change and just want to be with him. I couldn't see him sad anytime. So i told the new guy that we can't see each another anymore and we can continue to remain friends. He asked me the reason for rejecting him like that but i didn't tell him about my friend beacuse i didn't want to expose him. Then i talked with my old friend and told him that maybe we can try dating, let's see how it goes and he became very happy. But we both didn't tell anyone except our close friends that we were dating. The new guy stopped talking with me out of frustration for the next 2 months. But he agreed to remain friends after that. We both knew that he still had feelings for me and so I didn't want him to get too close with me as that would hurt him in the future. After one year, the new guy just couldn't control his feelings and asked me to break it off everything if i was not ready to be in a relationship with him. Since i was already dating, i told him no and we lost contact from everywhere. Even after that after few months i had to contact him through my friend for some issue and we started talking again in good terms. I thought that maybe staying away would make him move on from his feelings and i could then tell him that i'm dating someone. But idk how but he got to know it from someone else, and he got very upset. We had a huge argument on that and he said he never wants to see my face again because he liked me a lot and i broke his trust by not telling him about my dating thing. And i really didn't wanted to end things on a bad note beacuse i considered him as one of my good friends. I still want to be friends with him but he doesn't. i want him to be a part of my life and be friends with him but he is too hurt. How can i be friends with him again after so much has happened? and if we can't remain friends tell me why?
