Never stay overnight, it's too couple-y and gave me the feels when I did it once.
If FB, don't chat between meeting up. If FWB, try to do stuff outside of sex.
Don't let anyone treat you like the bottom of their "to do" list. You are worth working for, spending time with, and, of course, respect.
Honesty is the best policy. If feelings are a deal breaker for you both, make sure that's clear. And end it if you start getting feelings. As soon as possible.
Someone shake me. I just stalked Mr G's ex on Facebook and she's this well-groomed, cheerleader type. I am NOT like that at all; odd coloured hair, tattoos, no make-up, glasses, nerdy interests. He left her ages ago but I'm just so different to his normal type (he already told me he has always ended up with cheerleader type women) and I wonder what is he doing with me, really. Maybe I'm just an experiment. Ffs, it's so stupid. I shouldn't have gone looking. Old lovey-dovey comments on pics to each other. Stupidly, unaccountably, ridiculously jealous. Obviously he didn't just spring from the earth fully formed, we all have a past, it just felt weird seeing that today and I regret doing it. Gah.
Just to be clear, he has done nothing to warrant me feeling jealous, I'm just being stupid.
