I think once she saw how Clayton really lives, she got the ick.
You’ve been dating for 2+ years, suddenly when she lands, no sex in a month since she’s got there? Something seems very off about that. It’s even weirder that she acts like it’s not a big deal?
To make things worse, she mentions that she can “find another boyfriend”??
She doesn’t seem motivated into this relationship anymore.
Just remember too that other cultures wait to have sex until marriage.
