AITAH for calling my sex worker friend gross?

My (20F) friend (26F) is a sex worker and has been for several years now. She has a small selection of clients that she communicates with on a regular basis, as well as sites where other people can purchase content from her.

One of the clients (39M) is married and has a family. They've been communicating for some time and he's spent a lot of money on her. She knows that he has a family, he was up front about it from the start. She also knows that the wife (28F) doesn't know and she finds that even more enjoyable.

We met for dinner yesterday and she was boasting about how much money she'd made this month. I'm happy that she's doing well for herself, but I hate that she's breaking up families to make that money. She then dropped a bombshell on me, she met up with him last week and he told her that his wife is pregnant again. She was showing me pictures of the wife and laughing saying he has to put up with seeing her face everytime he wakes and not hers.

I couldn't stand it anymore. The unnecessary bashing of this young woman. It was a public setting, so I didn't want to cause a scene. I said "You've let this money go to your head, you're a nasty creature who can't be happy unless she's ruining someone else's life. Grow up and find clients who don't have a family to provide for". I left the restaurant after paying my share of the bill.

I got a text later that night "It's not my fault he wants me more than he wants her, I won't be cutting ties with him because he's a good lay and pays good money. I thought you were a girls girl, I guess I was wrong".
