Did my buddy try to seduce me? I'm straight...

Alright, so I need some cold hard feedback from you guys regarding a buddy of mine and my suspicion that he's secretly bi and actually tried to seduce me with the help of a gay friend of his.Some background:I've known him for about a year and a half now and we've became pretty good friends. He considers me his best friend and I could consider him the same, despite some reservation to feeling there's absolutely more to his life and story that he's never revealed to me.Anyway, everyone else I know who is straight takes one look at him, or him standing next to me (I consider us both handsom guys) and they immediately think "gay lovers" or in his case he like of looks like a porn star.. The way he dresses and his level of physical aesthetic...etcSome 'flags' -He used to call me almost every single day, and I started to get seriously annoyed with this because I ignored about 80% of those calls until he finally stopped. I thought of this as just part of his personality and need for attention because he lives with just roommates, so I just looked passed it.He got me and a female friend of ours to nearly hook up, and then later on when he invited me to hang out with him and her, he tells me to meet up literally 1 minutes before I can no longer go. When I asked him about it and her attraction for me he denies it, and this is where I started to think "Is he jealous or being possessive over her?".. after all he's close friends with her.I told him I'm moving to another state soon. I think he believes I'm leaving forever. His response was simply "Farewell my friend."Now here's the actual story that has me VERY concerned that he'd actually try to seduce me.He met some new friends who happened to be bi. A few weeks back he told me a little about them, and he made it sound like they're cool people to hang out with. Then one night he invited me to roll with him. We'd done that a few time before, just him and I while being down town where the bars are at, talking to chicks and what not- this is what I thought the night would look like again, hopefully with me and a sexy girl at the end of the night. Anyway, he tells me we're going to hang out with his bi buddies, so I said sure. I drive to his friend's house, and it's immediately apparent the guy is gay. Lets call his bi friend Stan, and my friend Bill.Stan's house is pristine inside. Extremely well kept and designed. We hang for a little bit and then we hop into Stan's wicked ride to pick up our molly. We drink it on the way back to Stan's house again, and by the time we get back there I'm completely in the throws of the drug. I can't remember why exactly we went back to Stan's appartment, but we were there. Bill takes his shirt off because the cool air feels nice, so I do the same. We seem to be waiting for something, and as everything slows down for me, Stan seems anxious, pacing around the house quickly, walking in and out of the house...etc Bill's just relaxing across a sink, and that's when the paranoia kicks in.I immediately start to observe everything, carefully choosing which cups I drink water from...etc All of a sudden I feel the need to puke, so I puke, and I wonder to myself "Was the confusion with which bottle already had a dose of molly designed to put two in me?" Later on Stan walks over does like a quick 1 second massage on my shoulders and asks something like "How ya feeling?". If it were straight guy I'd be more comfortable with that but I'm rolling, with no shirt, and he's gay and he's touching me, and I'm already paranoid... that freaked me out a bit more.I walk over to use the restroom, and the moment I walk over Stan's sitting there taking a shit with the door wide open, while Bill talks to him from the door, looking at Stan as they chat like it's no big deal. I'm immediately repulsed by this and I just walk away like "What the fuckk"Anyway, I can't help but walk and talk slowly, and some how we're back in Stan's car again going to a gay club. I've never been to a gay club, and being a straight guy I actually feel queasy seeing guys hooking up. It just bothers me. But I'm taken by the positive feelings of the molly so I'm just like "Why don't I just learn to be more accepting and go with it. I need to experience a different setting." Then Bill's turning around from the from seat, patting my knee and saying something like "Whatever happens tonight, just trust me. Just trust me with whatever happens." That doesn't really help my paranoia. At this point I'd become suspicious that because he thinks I'm leaving forever, he might as well try to leverage some molly to see if I'm bi curious.I found out earlier that night that Bill had spent many nights at Stan's house. Bill had a decent excuse, but the end of the story will reinforce my suspicion.So we get to the gay club, and I'm not really enjoying myself, having men faintly touch my ass or doing similar things..etc so I get Bill to leave with me to go down town. The entire rest of the night is hard to enjoy with this idea that I don't want to believe.My car's still at Stan's house, so I think "Aw fuck.. They had me drive there to have an excuse to get me back to the house when the night is over."Any touch, gesture, arm rub..etc I'm moving away from them. Bill and Stan's arms rub while they sit next to each other, and Stan stands pretty close behind Bill in certain situations..etcWe get back to Stan's house, the molly is wearing off, I don't get a feeling that I'm being forced into anything, more like 'situationally exposed to availability', so I just sleep on Stan's couch......... While Stan and Bill share his bed.....................In the morning I go to use the rest room, and Stan's bedroom door is slightly open (It slides in and out, it's not a normal swinging door. When I leave the restroom, the door is fully closed.I get my keys and leave.If my friend is bi, I really don't care. I'd much prefer he just tell me and carry on being friends. But if he's hidden that and he's now tried to see what my reaction would be under the influence of molly in his gay friend's house, and by taking me to a gay club (he's been there before with Stan without me).. I'd never speak with him again.What do you think? Thanks for your feedback!
