I'm married to a man who may be gay

"I was scrolling through my hubby's phone and I came across love messages between him and his boss, who is a man. At first I thought maybe he saved the name on the phone with his boss' name but it was actually him. I was so shocked and it took me a while to confront him. When I eventually confronted him about the text he said I misunderstood it. I'm not an illiterate I know what I read. We have a 2 year old son and now I'm scared to leave him alone with him. I don't want him to infect my son...worse still molest him. I don't even know what to do right now. He reads this blog, hopefully he sees this.
