I think the fact that you have allowed him an affair means you are being more than reasonable . . . probably even too lenient.

To answer your other question, I don't think it's very classy to keep reminding someone of how you're tolerating them or giving them rent-free board for example, even if you are doing it.

There's this story in my language about a guy who gives a homeless man some slippers. Every day he asks him how are the slippers, are they comfortable? etc etc. Eventually the homeless man gives them back, saying he's better off barefoot than continually affirming the guy's good deed.

Hope this answers your question?
