AITAH for freaking out after finding out my pregnant wife used to be a prostitute?

I’m 29 and have been married to my wife, who’s 32, for almost four years. We have a 3-year-old daughter and she’s about 5 months pregnant with our second kid. We always thought we were pretty open about our pasts, but I just found out something that’s really messing with me.

Last week at a family gathering, my wife’s cousin, who had a few too many drinks, said that my wife used to be an escort. Not just a one-time thing, but she was doing it regularly in her mid-20s. I had no idea. When I talked to my wife about it later, she broke down and admitted it’s true. She said she was in a tough spot and needed the money, and she was scared to tell me because she didn’t want me to judge her or leave.

I’m feeling really angry and betrayed. It’s not just that she did something like that, I get that people have their struggles, but we’ve been married for years and now we have kids. I feel like she never trusted me enough to be honest from the start. I freaked out and told her I need some space. She’s now staying with her mom, and her family is saying I’m being immature and that I should just get over it. My own parents are telling me to let it go for the sake of the family.

I know everyone’s saying different things, but I can’t shake off the feeling of being left in the dark about something so big. Am I the asshole for being upset and wanting some space?
