Tricky scenario '33F'

I'm a 33-year-old woman who’s often described as attractive, popular, and fit, with plenty of friends and a generally cheerful disposition. Recently, I entered into a wonderful relationship with a 39-year-old provider, and I genuinely love him. He’s sweet, a fire sign, and very attentive—he’ll bring me food and happily give me foot rubs every night if I ask, as well as take care of my bills. He always comes home on time, and we’re approaching four months together. However, our intimate life has dwindled to once a week, if I’m lucky. When I ask him about it, he insists that everything is fine. It used to be four or five times a week, which is why I started checking his phone at night. We both have each other's passwords, so it felt justified. In his deleted messages, I discovered that he was using an escort text line to request a quick visit. This has left me heartbroken. I tried to bring it up with him, but I was hesitant to admit that I had looked through his deleted messages. I asked him to communicate with me if something was wrong or if he wanted to take a break, but he acted oblivious and wanted me to clarify. I couldn’t bring myself to do that. I’m truly in love with him, and I recognize that no one is perfect. The thought of breaking up is daunting—not only am I financially dependent on him, but our families are intertwined, and we’ve been together for three years. How should I go about confronting him?
