How can I get out of the friend zone after hooking up with one of his friends?

About 7 years ago I met him & we become very close friends. We were close for a few years, until I set him up with my best friend at the time. When they first started dating we were all great together. Until the first time they broke up (about a yr and a half into the relationship). I took his side and she stopped talking to me. Around that time I saw a side to him that I had never seen before, and I started to fall for him. When they got back together she made him delete/block me completely, in retrospect I think it was a good thing seeing as my feelings probably would have messed up our relationship. We ended up not talking for about the last 2 years, and each moved on with our lives. I moved half way across the world (11 hr flight) for school, but I never really forgot about him. About 4 moths ago while I was back home for the summer we met up thru a mutual friend (actually, we run in the same group whenever I'm back home). I then found out he had recently broken up with her (3.5 yr relationship). We got back to being great friends over the summer and we spent almost every day together for 2 months. At first I wasn't sure of my feelings towards him, and I hooked up with one of his friends (He also hooked up with about 3 of my friends). Idk if that will effect anything? Long story short I'm currently living across the world from him (about 11 hr flight). As soon as I left a month ago to move back here after spending the summer back home I realized my true feelings for him. He just landed a few days ago here for a family emergency and he's in a really bad situation. I saw him last night and all my feelings became truly clear. I know he's currently in a really bad place and I wouldn't wanna take advantage of him. But should I tell him my feelings now? at the airport? or never? Or I can wait 8 months till I'm back home to tell him? he's only here for a few more days. I know him so well and I know he's going thru a lot right now and just last night he told me he thinks it's too soon for him to start dating again. But I feel like we are so close it wouldn't even be like dating. He's such a great friend, and I know he loves me a lot. Also I'm pretty sure he knows how I feel about him. People are shocked when they see how close friends we are and how we always keep out distance (physically).

Now isn't the right time, not he's just back for a family emergency for a couple of days. I think that would be too hard on both of you to tell him at the airport how you feel then watch him get on a plane! I'd let him know you're moving back in 8 months time and that you'd like to hang out with him more then, maybe talk to him like on the phone or email too, see how he's doing, just so he knows you're there .
