Well, I did it, I confessed my feelings.
It's a no...but, I think in that evening we strengthened our connection as friends. We were friends before, and I think we are closer friends now.
So, while I am disappointed, I am very happy to have him in my life as a friend. I admire him greatly, and after I told him how I felt, he made very sure that he explained his position, and that it doesn't change anything. We are still friends, good friends.
I'm concentrating on being grateful for that. It does hurt a little, but that is normal. Those feelings will fade, and I'm lucky to have such an amazing individual in my life. I definitely have room in my heart for another good friend.
Thank you all so much for your advice and for listening. It really, really helped.
Best of luck to you all, and I'll try to help out others here in any way I can.
