I am willing to take a contrarian view.
(1) Could it be that Paraguayan discovered that @Unicorn was trolling around on this website and perhaps hiring escorts himself? Was @Unicorn faithful to him, or not? Did it therefore create an assumption in the mind of Paraguayan that it was OK to sleep around? I am inclined to think that this is what happened.
(2) If Paraguayan was a resident at the home, it is not that easy to kick him out. Depending on the state, @Unicorn may need a court order. You can't just throw someone out from one day to the next, change locks, etc. Impossible!
