I feel really bad...

Yesterday I think my friend tried to come out to me when he asked for something very personal of me. I acted like he was kidding and said "why do you always say so much gay shit" he scared me because I felt my insides stir when he asked I responded in the only way I knew how.His only response was a simple "ok..." and walked home... I feel really bad and spent all last night looking up how I felt and what I had done. I think I watched my world crumble around me as my white picket fence dream faded... I'm still scared and I want to be there for him I just don't know how to say it.
