I was given a very specific (but non-inclusive) list of people I was not allowed to bring home. That included any and all women, naturally, but also included any and all men of any colour darker than germanic-european-white, and indeed any men of a religion other than young-earth-creationists.
Breaking any of these rules while still living in the house would have meant my expulsion from the house. I’d like to say my mom wouldn’t have allowed him to kick me out but I really don’t know.
Backing all these comments that say it’s about communication. If I found out my partner has been selling nudes, hiding it from me, and also hiding the money? An unforgivable betrayal of my trust and our relationship. If he came to me beforehand and we discussed it and the money went towards our mutual goals, it would at least be something I’d consider.
The whole point is not hiding it from your partner. Discuss things before you do them.
