I think my coworker/friend wants to fuck my man?

So I’ve become pretty good friends with this girl, call her Amy. Amy is cool and we’ve known each other for about a year. Recently I let her start hanging around my man. She CLEARLY has the hots for him, but my man is ultra fine and I’m used to girls staring. She has started crossing lines tho. She straight up talks about shit like her underwear she’s got on, how horny she is, blah blah bullshit. On top of that, she’s a hugger and boy will she hug tf out of him. He barely hugs me but will return her hugs.

Anyways, I’ve told him that it makes me uncomfortable and that if roles were reversed, he would be livid. He told me he has zero interest in this girl, and that I should trust him. I do trust him, I don’t trust her. And I tried to remind him that when one of my guy coworkers follow me on insta, he got jealous, but I’m not supposed to be jealous of Amy? Should I be jealous or madd? And I do, at who? Her for sure, but my man too?

I don’t even know what I’m asking for with this post. Maybe I’m just venting. Idk. I know we’re supposed to go hang out with her and another person later tonight and I’m already mad about what I know I will see but I’m not supposed to be mad.

Also, Amy’s sister is like my best friend and I’m worried if I piss off Amy, I’ll lose my friend.
