How do i unloved him?!

Too much boredom will make you more into the social world.I met this guy from yahoo chat rooms before way back 2012 August. We chatted, we had talked from different things but we're civil to each other that time just a plain talk, no sweetness, no strings attached. I like him actually he's cute so i get attracted easily but he seems don't like me so he didn't spend much more time with me. Time passes,everyday i send him messages but he didn't even mind to reply so i conclude he doesn't like me so i delete him in my yahoo list. Almost one year passed,i actually forget about him. But one day, one guy send me a message on my facebook, i know it was him. I was surprised! really surprised! he said he always check me on my yahoo but he never see me online anymore so he make a facebook account and search my name along with his other girl friends. So he did found me again. Not like before that we're civil, everything turns into like we're best friends. We share different things about life, we had laughs, we fight like a cat and dog but still we remain very close. He's a very patient and gentleman while i'm a crazy and bad mouthed girl (haha!). One time he said that he already liked me. He was actually my best friend, he listen to my craziness, he's my shoulder to cry on even he's ten thousand miles away i felt his inside in my heart. We then became lovers. I told him i wanted to get marry this year so i asked him to get marry once we meet since we know each other for long time even in chat only but he refused, he said he's still have an issue with his life and cannot marry this year. If i want to marry and love him, i need to wait for him for 2 years until he finish his issues. But i was really desperate and crazy, i told him if u can't marry me this year so i will find another one, so i did. I left him all of a sudden. Unfortunately the man i found who i thought was more better than him is more crazy than me so we didn't work out. I message my best friend again and told him everything. I know i hurt him so much, he said he was very worried about me. He still accept me with open arms and he still says he loves me. Maybe i was very lucky to have him as my man, very understanding, patient, loving and serious. But i misunderstand him from his sweetness towards his girl friends. I really get jealous. Maybe i was really crazy. When i'm checking his facebook i always read those exchange messages and post from him and from his girl friends. I asked him about it but he only replied that i'm not new with that. I know his serious towards me because he ask permission to his mother if we can get marry this year and he even let his mother talk to me thru skype. One day i don't know what happen, he was gone suddenly. 4 days passed he then suddenly send me a message saying that he knows that i'm mad with him because he was gone suddenly, he said he don't have any time or chance to be online so he cannot send me messages either, but i didn't replied to him because i don't want to fight with him. On the next day i saw him online until the following days but we didn't talk to each other. I really feel bad about him. I try to check the facebook account of his girl friends then it makes me more feel bad about him by seeing those posts that he never missed any day to get in touch with his girl friends while me, he just left me hanging and telling me he don't have any chance to be online. So i freaked out, it really breaks my heart that there's some girls who's much more important for him than me. I bad mouthed him, like i almost cursed him and also his girl friends i bad mouthed trying to destroy him towards them. He deleted me from all his account but he still keep his girl friends from his social accounts and that's really hurt me so much. If those girls can make him more happy then so be it even it hurts. All our plans and dreams are wasted because of my jealousy. It's just really hard for me to unloved him. I just wish him all the best :,)
