Bestfriend is insanely “boy crazy”

To preface, bestfriend & I are in our early 20’s, I’m 22 and she just turned 21. She just got out of a 3yr relationship in January & I’m married. She also just moved from one province to the province I currently live in.

I guess to simply explain the issue at hand is she is insanely “boy crazy” to the point where it’s not just my husband & I that get annoyed with it, every single other person in her life that she sees on a regular basis, is also fed up. She’s been back in this province for I want to say, 5 ish months, and since she moved back there has been a handful of different men that she’s talked to, and all of the situations are the exact same to the T. She finds them either at the bar, dating apps, or our friend group, she takes an interest in them, all of them to the average person, can tell right off the bat that they are not interested in her what so ever, however she convinces herself they all want her, psycho-analyzes every post & convinces herself that it’s about her and the man is in love with her, then sends herself SPIRALING, sobbing crash out sessions, when they don’t give her the attention she wants, are talking to a different girl, or when she finds out they do not like her in that way. All she talks about is men, everything she does is to get attention from men, she has zero regard for her own safety & goes home with random men from the bar ALL the time. It’s gotten to point where a good chunk of my husband & I’s friends will not come to events, parties, hangouts, if she’s there. And it’s difficult because we love her dearly, she is a great friend, and we enjoy having her around, however we genuinely cannot deal with this behaviour anymore, it drives us insane. I also understand that yes, she just got out of a long term relationship and she’s single for the first time in awhile, but it gets to a point. We’ve tried talking to her about it, even some of our other single friends have tried talking to her about it, but it goes in one ear and out the other. I’m just at a loss, I have no idea what to do, the behaviour needs to stop, we want to keep having her around but the way she’s so obsessed with male attention is unbearable.
