Cheating Husband

My husband forgot that hotels.com app was on my phone and I was notified that his room was booked for a weekend I knew nothing about. When I confronted him he tried to turn it around on me. We were temporarily separated and trying to work on it. I asked him to be straight with me if he was talking to someone else and he lied. He made me feel like I was overreacting and couldnt trust him and he couldnt be with me if I cant trust him. Im so mad at myself for allowing myself to believe him knowing full well that he has lied too many times and I shouldnt trust him. But I still gave him the benefit of the doubt.

I deserve so much better! Even if Im alone, Id rather be alone than be with someone who treats me like this! why have I allowed him to treat me like Im not worth more?
