Heartbroken...need a friend 😢

I just found out a few days ago that my husband been having an affair for a few years and I never knew. To top it off the girl got his name tattooed on her. I’m soooo devastated!! Him and I been together for 17yrs. Since high school. Been married what would have been 10yrs next month. Over the years I’ve heard he had multiple relationships with other people but he denied everyone of them. He is very persuasive. I just can’t understand how he loves on me the way he does but then does all these things. After I confronted him the other day he denied everything and was yelling and screaming on the phone with me. Little does he know my best friend told me because she ran into the girl. I told him it was over and I can’t do it anymore. I texted him today to mention a bill was due that he pays and he blocked me. How is he mad that he got caught??? I’m so sad I can’t even eat. All I know is him. I need a friend. I’m so sad.
