My (29F) husband (31M) won't let me in a room with another man even at work

I (29F) joined a new company last year June and am an account assistant, so I work with a couple of other departments. I have a great relationship with everyone, so no issues.<br><br>My husband (31M) has been working part-time since he was let go of his full-time job, but now he's found a full-time job. Luckily for him, after a week or so at this job he found out his company is a client of mine and I'll have to work with him in these projects. I was great as he'd been struggling to find a job and I'd even spoken about the projects in the car ride home.<br><br>But when I said there'd need to be meetings and calls with his team he wasn't okay with it, he then said he won't let me in a private meeting or call with a man. I said there's no other women in this department and it's not like I have a choice with who I work with as it's assigned to me. But he said he doesn't want to think about me in a room with any man or on a zoom call with any man without him there as well. I told him that it doesn't work like that, he won't be there and he needs to let it go and he did.<br><br>However, a couple of days ago we were discussing the projects and he said he doesn't want to think about me having to say hi to him everyday or him listening to me speak. I said it's work and it's nothing to make a big fuss over and nothing's going to happen. But he said what if someone there has a crush on me or what if someone tries to hit on me. I said if anything like that happens, I'll handle it but he just won't let go of the idea at all. <br><br>He was really calm about this and said he just wants to protect me. I said he needs to let go a bit but he says not on this and even if anyone saw him being okay with me working alone with a man would see him as a lesser husband for letting me do that.<br><br>I'm a bit lost on what to do here. I am bringing this up with my supervisor that he has an issue with us working together and will ask for someone else to work on the project. What would be the next move after that? <br><br>**TL;DR:** my husband won't let me interact with men even at work.
