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.
To be fair, I too would have the ick if my boyfriend had pets that he were so allergic to that he expected me to do all the clean-up for them without prior negotiation.
