How do I gain his trust back?

I have to kind of detail this story so you can give me a clear answer.
Okay, so I met this guy about a month or so ago, and I really really like him and care about him. Unfortunately in the beginning of our friendship, I had led him on to believe that I didn’t have a whole lot of limitations as far as what we could do inside the bedroom, which I have limitations for because of my faith, which I have been kind of ignoring for the past year, but I’m following again. He was even more upset that last year I did that kinda stuff with someone else, and now I don’t want to now that I’m with him. I didn’t like him at first so I went along with what he said, and even sent him dirty texts. But a couple days ago when I realized that he was actually planning to do those things on this date today, I realized I was keeping a serious thing from him and it was going to hurt him if I didn’t tell him right now. Well I did and he didn’t take it very well. He has some trust issues, and his heart has been broken before. I never ever want to break his heart, I care for him so much. But he’s very mad at me for keeping this from him. He’s treating me a lottt different now… I begged him to give me a second chance, and thank goodness he did. But I don’t know how he is expecting me to be like when we hang out or what he’s looking for? Just my honesty? He’s pretty certain he’ll know when we hang out.
Some quick advice would be sooo appritiated.
Thanks you so much!
