I believe God WILL work a miracle in your life, thats what I am praying for!
On the one hand she wants to have that special connection with you and has needs and the other she knows that you have needs and one of them is time and
to have a little space in that area. She needs to respect and honer that.
Hang in there, your doing the right thing and the Lord knows your heart. I think she needs to cope with sex just like you do just in a different way!

God Bless
