In Love But Never Together

So, I have never ever been in a relationship with another person you know boyfriend & girlfriend.

So I always felt that I have never been in love because I used to think in order to be in love with someone they had to like love you back or at the very least you two had to be together in that kind of a way.

But recently I have been wondering if I was in love with this friend of mine. We were extremely close. I can kid around him, feel completely comfortable, and can talk to him about everything. Well actually I used to be able to do all these things with him.

Recently we moved apart and all of that closeness and camaraderie has stopped and well recently may be the wrong word choice, it has been 11 months since we have been apart and I thought it would get easier but I still feel lonely sometimes just because they are not around.

We were the closest of friends and never were together intimately I have never even kissed the guy but I care and love for for everyone that is a close friend but that's a general kind of love that I give but I seemed to miss him in another way I can't quite explain it so since I've never been in love before I wonder if I loved him in that way and feel really weird without him here?

So, I put out this question to anyone that may be reading this Can you be in love with someone you were never an item with?
