This girl and my husband

Ladies idk what to think. So Saturday my husband works alone (all day) just him and this girl (they’re around the same age) and I’m not comfortable with it. He’s came home telling me how she brags about how many dicks she’s sucked and how she’s been ran through by her whole town. She’s pretty so I don’t doubt my husband finds her attractive but I don’t trust that she won’t make a move on him. My husband tells me all the time that I don’t make him happy, I have all these problems, and just complains about me almost every day. We just had the littlest argument last night and he called me a cunt and told me he wanted a divorce. I’ve told him how I felt about him working with her alone ( I know it’s his job) and he told me he would be uncomfortable too. I’m not sure what he means by that 😭😭😭😭
