Strange text messages

So I asked to borrow my husbands phone because i had this verification code go to his phone because I couldn’t get into our Netflix account. So I put in the code, no problem and then a text message pops up at the same time from a girl names Rissa. I read the I see that they’ve been texting each other and that she was saying how he’s so strong and that he can pick her up. He replied saying how he can pick her up and pin her against the wall as well. She then said “omg you are sis strong then I don’t have to worry about you picking me up 😉 ;)” I got furious because I told him that those texts weee very inappropriate and how I’d never message any of my male friends nonsense like that. I feel like I don’t even want to be with him anymore because I’ve never had any issue with trusting him and now I see this and I feel like I don’t even know what to do. I even threaten to kick him out. Am I wrong to feel this way and what I said?
