Search Results: loose interest

So he was a good close friend that I met at the beginning of this school year and he asked me out almost 2 weeks ago (let's call him A). This was 4 days after we had hung out with our mutual friend and then they left so it was just us and we had a great time (as friends) and he seemed interested but a little off at the same time but I had so much fun and I thought I developed feelings. I knew he liked me before that like 2 months ago (staring a lot) but I thought he had lost interest after a little.

Anyways, he asked me out and I was pretty shocked because I had no idea (I thought he had lost interest^). and I rejected him out of shock even though I think I like him. but I don't know if I like him just for the attention he gave me. I do not just feel bad for him. He's avoiding me so I wrote him a letter (wow this sounds so middle school - we're in high school) that said I liked him and stuff which I said to read alone on but he read it with his friend and then I talked to the friend he read it with (let's call him B- B is super nosey ugh). So B said that after reading it A said "she rejected me so why should I do this" or something like that. A said to the mutual friend that we both hung out with^^ that he thinks I just wrote the letter because I feel bad for him but I do not, at all.

What I want is just to go on a date and see how I feel about it. I offered to talk the other day in class but he said no kind of harshly and walked away. I want to give him space but I don't want to loose him (in both a friend and relationship kind of way) what do I do? Do I give him space or confront him/explain and we have more than half our classes together. I know he's hurt but I really don't want to loose him (that sounds selfish, I know but this whole thing is just so stupid) - I want opinions too by the way, thanks (: sorry it's so long and over-complicated
