I don't mean to be picky. From what you've written it doesn't sound like you have an overwhelming love for your husband and will be devastated if the marriage ends.
I think you need to be honest with your husband. Don't commit to trying to make it work unless you are in love with your husband and want to stay with him for the rest of your life.
My advice would be to take some time on your own to think and reflect about what went wrong and what you want.
