What should I do??

Okay so I talk to this guy (AS FRIENDS). I have a bf (its a little more complicated than that tho but I’ll just call him my bf..and he is 100% okay with me talking to guy friends). Well, recently my guy friend admitted to having feelings for me. I told him sorry, like I have feelings for someone else but I’d like to remain friends. He understood. Well, a couple days later he basically tried saying I was HIS and getting upset and jealous after talking to my boyfriend. He then LIED, telling my bf that I said I had feelings for him too. It caused a fight between me and my bf, to say the least. My friend apologized, and it’s been okay since then. But TODAY, he found out I was moving to a different city, like 40 mins away (which I have no control over), and had a complete freak out. He called me saying “fuck you” and stuff like that. He then told me he didn’t wanna be friends anymore and, and then turned around asking me to forgive him. He’s being explosive and mean and idk what to do.
