False sexual harassment allegations. Say something or stay out of it?

I new girl started working at my work. She instantly started flirting with another co worker who me and my husband have been friends with for years (I’m the one that got him the job here).

She clearly kept flirting and trying to date him and he was hesitant because he didn’t want a awkward work environment if they didn’t work out or got together then broke up. This is what he told me and my husband but we thought he should just go for it, since he has been single for so long since his ex cheated and broke his heart. And I thought this girl was really cool and down to earth since me and her were becoming close friends at work.

After about 3 month of her flirting SHE asked him out and he agreed. Apparently they went out to a restaurant he paid and they ended up kissing. Then the next weekend they went out again and this time they had sex. This is what she told me because me and her have become friends too.

After that i guess a couple days later she told him she just wants to be friends and is seeing someone else now. So really the whole relationship or fling lasted maybe 3 weeks. He said ok and just didn’t talk to her at work and just ignored her since they weren’t really required to talk at work. Then he tells me our boss and HR called him for a meeting and she reported him for “being creepy” and “making her uncomfortable” they called it sexual harassment.

He says he literally has not said one word to her since they broke it off. And I can confirm this since I work with both of them.

I ended up pulling her aside and asking her what happened and what is he doing that made her report him. She tells me he just creeps her out since they slept together. And sometimes she catches him staring at her but then he looks away when she looks at him.

I personally don’t think this is sexual harassment and she is wrong to report this and try to make him loose his job. Would you say something to HR or stay out of it?

And before anyone suggests they can be put on separate shifts to not see each other. That is really not possible with this job. There really is only one shift and it’s a small place so impossible to separate them.

Also for the people who might say “didn’t you just post this” yes I did. But I deleted and reposted because somehow it posted it in the wrong forum on this app.
