Prostitution Solution Not!

My husband and I have been married for 7 years with two kids. I grew up in an abusive home leaving at 14 and went into prostitution four five years before getting my life straight. I moved to a different part of the country starting a new, getting a great job in sales and making excellent money. My husband has always said that I’m easily the best sex he’s ever had. He loves how I love him and fuck him. Well someone from my past told him I was a prostitute and he has dumped me and did so using language I won’t repeat here. He also slapped me so hard it left a mark on my face. I understand him being shocked and upset but I never told him of my past because I’m ashamed of it and too, my past is none of his fucking business. I have never asked him about his past and he never asked me about mine. He’s filing for divorce. I’m heart broken. Am I wrong?
