Everyone knows that people want what other people want. My BF's ex wants him back and the reality is that she is objectively gorgeous (I mean she's a hard 10, she looks like she was engineered by the gods and I am maybe a 7 at best).

Aside from fake it till you make it, any other advice?

Also for clarification, we've been together for over 2.5 years and they haven't been together for at least 4. I trust my bf but looking at her makes me wonder what he's doing with me, especially because she has contacted him trying to set up a meeting.
