Guy's Behavior

Close guy friend just unfriended me on Facebook? Why?

A close guy friend who I work with just unfriended me on Facebook. When I say close I mean I have a key to his house, we have shared Christmas presents, decorated his tree together, movies, lunches... Now, this man claimed to be bisexual and is in a long term relationship with another man. But for six months he did not tell me and gave out signals to me. I eventually told him I had feelings for him and he never acted on them and never told me about his relationship. We stayed friends, but I told him to keep the flirting to a zero. Eventually he invited me to his house only for me to find out through his boyfriend ( which he hates that term) that they were together. I was devastated, but stayed supportive. I could tell he was very uncomfortable with me knowing about that part of his life. As months went one he still sent out mixed signals to me. Acting jealous, playing "couple" when we out to go do errands together... and so on... But because my feelings never really went away it was hard to be around them. I Started to take space, and one weekend I went out with my best friend and had a grand time... posting on fb and snap chat (I was a little tipsy) and those snaps may have included some guys we met at the bar... That Tuesday morning before I went into work I saw that he removed me from Facebook and snap chat.. Why? I'm so hurt and tired of the games.. please help with any insight. Thank you.
