<human>: I'm not an english major and my grammar/punctuation sucks I know, but please see past my errors and choppy sentences.
 
Ok so here is the situation my boyfriend "Rob" has been friends with "Sam" since they were little kids. No one gets them like they do, even after 6 years apart they fall back into themselves the moment they start talking. Sam has been out of the country since before me and Rob got together. I have only met Sam once, 3 years ago. There was almost a year gap where they didn't talk at all. There was no issue just both busy with their own lives. Well Sam is going back to their home town for the holidays and he's planing on staying with us. I didn't have any issue with it until certain tid bits of their conversation caught my ear. I wasn't eavesdropping it's a small apartment and Robs voice carries, anyways Rob told me what was said later. But Sam thinks I'm "hot" and has expressed and interest in seeing me with less clothes than more. They have also had detailed conversations about mine and Robs sex life. The details on that are fuzzy because he won't tell me what was said. But now Rob is acting really weird, another guy tries to flirt or hit on me he goes into macho mode and wants "throw down" but his best friend blatantly tells him he want's a go and that's totally cool with him. Now I don't know if they are trying to get a threesome going or if it's a voyeur fetish on Robs part but I'm not game. I love Rob and feel a little betrayed that he would in a sense offer me up like that. I'm not a prude, in my single days the idea of a threesome was sexy. But after sharing my life and bed with one man faithfully for over 3 years it's just not appetizing any more. So any advice or what have you is greatly appreciated I can't really talk to anyone in my immediate life about this because or obvious reasons.

Can you condense the text into three sentences or less?
<bot>: BF's, BFF has a thing for me, normally jelly BF seems to not mind and is acting like he wants to do some kind of sex act with the 3 of us. I'm not down.
