lake How do you know when an EF wants to become a FWB?

I think that if you are already emotionally involved with her and she with you, you will be able to tell by little things, like glances or longer looks, more touching, and by what is said and the way in which it is said. There's also other body language to look for, too, like if she leans into you more when she's talking. It will probably get to the point where you're both wondering how and if you should take it to the next level, especially if you're both in bad marriages. Tell me, because I'm very curious, what comes after FWB?there
