I need to know if I'm over thinking things..

I just saw messages between my partner and his friend..

My partner said he has a girl coming over and his friend asked if she was coming over to pick something up. My partner then deleted the messages and I don't know if he ended up replying to his friend..

I really hope I'm wrong in thinking it's about sex...

what do you ladies think..?

The reason I'm worried is because we had an issue a little while ago where he took acid and was going to get a hooker...
