I didn't know your friend in person, but I'm sure he was a very nice guy and that Ты guys had a lot of fun together.
I'm sure he saw Ты as a great friend too.
Anyways, whenever Ты feel the need: Ты can always talk to me. I'll be there to listen, give Ты Совет when Ты need it, to laugh with Ты and to Показать Ты that I care.
Ты are a great person and I'm sure your friend thought so as well. I'm sure that he'd want Ты to be happy and enjoy the rest of your life, even if he can't be with Ты anymore.
Always remember that Ты are loved. (:
