What would you do?

My husband and I have been together 5 years, married for 3. After we got married, maybe within the first year or two, he admitted that he was bisexual. He has done stuff with males previously (before he was 18) so years ago. But he claims he’s only into certain men. Like James Charles is one of his crushes. Those type of men is what he’s into. Our marriage has already gone through its issues and our trust is a little broken. He had to leave for work and will be gone for at least 120 days for sure. He’s obviously around nothing but guys which is fine whatever. Any woman would love that, but yet I am worrying that something may happen. Not because he’s cheated or hasn’t cheated. But because he’s been acting distant since leaving and it’s put an even bigger strain on our marriage. He also watches trans porn I guess you would call it. It’s where the women have penises and vaginas. Not sure if I have the correct term so please don’t jump down my throat if I’m butchering it. It made me uncomfortable but whatever he likes what he likes I guess. Can’t unlove him for who he is. I’ve already committed myself and I love him that doesn’t change anything right now. He FaceTimed me the other day and his roommate was in his boxers (I saw because he walked behind my husband), and my husband told me that he sleeps naked as well as the other guy. This bothers me a lot. If he was straight it wouldn’t be an issue. But it’s making me worry. Also the guy always asks who he’s on the phone with when we are talking. I am a very private person and I haven’t told anyone about our marriage or what my husband told me 2 years ago because it’s his business and I don’t think he wants our loved ones and friends to know. So I’ve just accepted it and never had anyone to talk to about it. I’m telling my husband that I am worried something is going on due to all of these things bothering me and he reassured me nothing is going on yet he’s constantly leaving me hanging for this guy. They go workout, go to see movies together, and I’m left waiting to be replied to or FaceTimed. When he tells me he will talk to me after work I assume he has time but he chooses to hang out with his roommate that he is around all day everyday. It just makes me feel unimportant. I can’t help but wonder. Maybe I’m wrong and nothing is going on, but all of these things make me uncomfortable and my husband blows me off. So I am left dealing with it on my own (it’s to the point that I stay up at night torturing myself worrying), or I can bring it up and he just gets angry with me. I don’t know what to do anymore. But all I know is I’m tired of the arguments, the feeling unimportant, and just feeling like my husband got stolen from me by a man. Maybe he isn’t a threat, but I can’t rule it out and my husband isn’t helping just making it worse.
