Met her two months ago. She's in an LTR. She says she was unhappy on how things ended with her last boyfriend so she actively pursued a guy that fitted her and after some work, she got him to commit.

I know for a fact the guy is a provider and has beta written all over him. The girl, on the ohter hand, has no issues flirting with me, kino, and lets me do stuff that should be off limits in general but never gets pissed at me.

Subtle way to find if she's ready to jump ship, before I next her?
