Cheating husband

Does anyone have success with making a marrige work after one cheated? We both want to make this work. He also knows what he did was wrong and cant Express how sorry he is. After a few days of talking he has come to realize that the grass is always greener where you water it. And the past few weeks he has been spending all of his energy on her and not on me.

Side note to add we have been together for over 6 years and this is the first time he has ever done anything like this! He has stood by my side through me leaving for army training. Through a hip surgery, A miscarriage, a cancer scare <a href="">fertility treatment</a> with our first daughter and again now with this baby currently 20 weeks. He is willing to do anything to prove how much he loves me and our family. I'm in love with him still to this day and through talking we realized that once our first was born we stopped taking time for us as a couple.
