What is wrong?

I started a new job almost a month ago with a great salary and the hours are great as well. My husband does not like the fact that the administrator is a male. Who cares? I do my job alone in my office and the admin when he is even there goes about and does whatever they do!! Not with me. So my husband explodes calling me a cheater and a liar, said I told him the dude was in his 30s. I said no my coworker males are in their 30s. And he’s ok with them because they’re a gay married couple. However the administrator is married and he says that doesn’t matter that he will find out what’s going on (literally won’t find out anything not a damn thing is happening) I have a very mentally exhausting job and don’t have time to be bullied by the person who is supposed to shield me and make me feel better!! This is ridiculous. I gave up nursing school for this position because it pays so well. I’m livid he is acting this way.
