I’m not sure 🤔

So my husband is a photographer. I was very supportive while he was growing his business. He would tell me everything about his day who he had a photo shoot with when and where ( I didn’t ask he just told me) but then he started taking photos of half naked women and would and stoped telling me anything about his photography. He does all his business on Instagram so that’s how he makes appointment. And sometime when He’s texting someone and I walk in the room he quickly exits out and puts his phone away. He knows my password and everything that’s on my phone but I don’t know his password or anything on his phone. And when I ask him about any of his photos or just ask who he’s talking to he gets mad at me and tells me I’m crazy and I’m insecure. Am I being dumb?
