Communication is key and will help restore your sex life. Have you tried to talk to her, without talking her into sex? Find out what's going on for her, and in her life. Be gently affectionate, without being overtly sexual. Show her that you love and appreciate her. What is the reason behind her withholding affection? If you really want to know, listen to what she says. Don't get defensive, just listen, with a heart to heal. Ask her what you can do to restore your relationship. Tell her how much you miss the intimacy that you shared, and ask her what you can do to help her return to you. Listen first to understand. Then move forward gently. Tell her you love her, and you want things to work. I wish you the best.
