My wife and I have not had sex for over ten years. So this part of your life I could have no advice on. Either way I think you can work the marriage out.
Remember what you wrote the other day about gods plan on this subject, surely God can work anything out in your marriage if you put Him first in your life. Sex is one of the toughest things to work out with his wife for a boylover that is married. so do not give up hope. By the way I am going pray for you and your family and am asking others that I know to do the same.

God Bless
