Im bi, and i am in love with straight friend, iin

I am a bi male. I have a friend who I believe is "straight" but have doubts. Now ordinarily I wouldn't care about another persons sexual preference. But I have feelings for him. He knows that I am bisexual and has known since the beginning of our friendship. One night some months ago he came over to my home and we had a few drinks and talked like men do. We were watching porn and having sexual talk in general (not about us with each other). Eventually the conversation came down to falactio's. He began to get excited just as I did. He then stood up and blurted out that he just wanted to" @#$% my mouth". This totally took me by surprise. He then suddenly said "I can't do this" and left. He came over the next morning and apologized for leading me on and claiming the mixture of the drinks and the porn had him feeling horny....Now fast forward a few months to the present. My "straight" friend has now asked if can stay with me for a while. He was going through somethings with his children's mother (not wife). I allowed him, now the chemistry between us is a little weird. He does handle me in a way like a man would a woman. I have to admit I do play the submissive role to him sometimes; example. I love to cook. But since he has been here I find myself cooking more often. He allows me to feed food off a fork or spoon to him. We watch movies together in my bed. We talk about everything including sex, I mean we talk about it all. From the size even pics of each other body parts. He tells me all the time he straight and he would never be with a man ever. Yet from the outside looking in a person would think he and I were in a relationship. Just on how he handles me and touch me. He is very doting. I am falling for him. He is such a man. He takes trash out and cleans the home. Very clean and respectful. But I am confused. There is so many things that happen. I just don't know what to think. And I know for sure that how we are with each other alone. Is definitely different then when others are around. Well it's still the same just somewhat subtle. Please Help! Am I reading too much into his kind heart and ways misinterpreting them into something more geared towards my own feelings and desires.
