Could This Guy Be a Closet Gay?

Hey. I'm 19 years old and most likely bisexual. All I really know is I think, porn-wise, sex between a man and woman is hot, but lesbian and gay sex is way hotter. Wierd. Anyways, I had this peculiar situation happen to me last summer, the year I graduated high school. I started heavily smoking pot, and through other people who like to smoke pot, met this guy, we'll call him Jack. Now Jack used to go to my school, but ended up going to online schooling. I always thought he was really hot, was even pretty forward about it, and the responses were, as usual, vague and hard to piece together. For instance, one time as we were walking through the high school halls, Jack told me about how his girlfriend wouldn't blow him. I jokingly (but not really) told him that I would totally do it if she wouldn't. He suggested I tell his girlfriend that. Wierd. So, back to last summer, the "crew" would come to my place in the dead of night because my mom was at work and we all had weed. The two or three times Jack came through my door and actually hung out, we would always make eye contact, all the time. "Oh, better put on that rubber,' right? It get's better. We all stepped outside, smoking, and out of the blue, Jack asks me when my parents get home. I tell him that my mother won't return until we have to go to school. He replies with, "interesting." Followed by a long pause, and I respond, not knowing how to feel about it, "yeah." Wierd. Around the last couple of days we hung out, I was really trying to get into Jack's pants. Specifically, the last night we did spend together, I spent pretty much the whole night staring at him, kind of fucking with him, kind of trying to gauge the reaction. After about 10 seconds of eye contact, he turns away and squeals "queer." I just chuckle and pretend not to be slightly hurt. We all sat around in a circle in Jack's grandma's house, and I can't exactly remember how the conversation got to this, but it started with him saying he's not gay. Then he asked his friend next to him. He says he's straight as an arrow. He asks the next in the circle, and immediately I was dreading what I wanted to say. I wasn't about to lie about who I was, and I relaxed as I realized I was too high to care. So it got to me and I just kinda spoke, "I'm down for whatever, man." Everyone stopped what they were doing. One of the group interjected and said, "so you would fuck Jack's dog? You get off on that?" I replied, "naw, dude, that ain't me." We all laughed about it. But then jack said this: "So you're gay then?" I said, "Basically." He wanted to say something, I know it, because he went "I-" and as soon as everyone went silent to hear him, he froze, and then responded with "shit's fucked, bro." That got a couple of laughs. Wierd. I thought I had finally gotten my answer and offered him to come to my place after we all went home. Over text. No response. After the time I had alotted, I realized I had made a mistake and immediately apologized for being so blunt. No response. After a while, I found out from a friend that the situation "really grossed him out." I was also told from the same source that, when my friend had made a joke of him being gay, he got pissed off for the whole night. Wierd. Now, I like to think I have a lot of insight into people in general, but I cannot read this Jack character at all. What are you guyzez opinions? Any ideas on what the hell that shit was about? He also takes pride in being homophobic and is ashamed to have the same birthday as when gayarriage was legalized. Obviously, I'm no longer interested, haven't been for a while. But it was a question I was never really able to answer.
