I'm a 20yr old Bi guy and I recently ruined a very good friendship of mine with another young man when I randomly kissed him. We had known each other for only a month and we're still currently stationed in at the same military base. When we first met he was extremely shy and reserved but would respond positively to my jokes and small talk. He is from a rural town in Arizona and I'm from the District of Columbia. We had a lot in common listened to the same music played the same games and had a lot of the same morals and beliefs. He eventually opened up after the second week and would frequently come over to my dorm to hangout after work. He would say things like "I really look forward all day to come over here with you". And "I'm so glad I have someone to talk to because my room is lonely aahhaha." We would walk to the store together, workout together and he would sleep over on the weekends everyday until Sunday night. It got to the point where I had to kind of ask him to please leave haha.
Eventually it started to turn into a very platonic friendship. He would jokingly grab and interlock our hands, he'd sit on my lap, and we would even sleep in the same bed (nothing sexual tho). My straight friends never acted like this. When I would grab and hold him he never said stop or get off me or would fight back like my straight friends. He would let me put my head on his shoulder and his chest. He never talked about girls I'm not exaggerating he wouldn't bring up ex's or scope out any random girls. I would bring up girls and he'd change the topic. Also whenever we were in a group of friends and I would get up to leave to go to another room, the bathroom, outside or to just answer a call he'd follow me. Our horsing around got to the point to where our other friends would say stop you two look like a damn couple. Of course I had developed feelings for him.
Then one day he came over and started the usual horseplay. He hugged me for a while and he pulled away I just instinctively kissed his neck and check. We were still holding each other and I put my forehead on his and looked him in the eyes. He looked away and had a sad sort of disgusted look on his face. After noticing that I pulled away and told him I had liked him. He said like how and I said like more than a friend. He was surprisingly calm. He didn't hit me or fight back or pull away the whole 5 minutes I was kissing him. He told me I was an awesome friend but that just wasn't him. He didn't say he was gay or straight he just said that. He even still wanted to walk with me to the store but then he said its OK I'll let you stay here and think. He said he would come back and never did.
I texted him that night and said I was truly sorry and I hope I didn't offend you. He didn't respond to that text that day or my next one the next day. He unfriended me on Facebook but left the pics of us up and still tagged. Now whenever I see him he acts like I don't exist. My friends say I should just leave him alone and not say anything until he says something to me first. I don't want a relationship with him I just want my friend back. I hurt everyday when I have to wake up and remember that I lost one of my really good friends because of my own selfishness and inconsiderations.
Please this is very serious to me and I want as much advice as I can get to make things right.
