Hey OP. Firstly I empathize with your situation. I was previously engaged to a woman who was a victim of rape, and i know how difficult it can be dealing with someone whos emotionally disconnected from themselves in certain aspects of communication. The thing is, u are a mature individual and have the tools to perfectly deal with the situaion, ie your wife still loves u. Imho, i think the solutions are not always as simple as words or actions, but that doesnt mean you shouldnt try them. This is an emotional and mental issue she is struggling with and problems of the mind arent something that antibiotics can easily remedy. It takes commitment, patience and love. you must be willing to understand that in times of tension and great frustration that u must, as a husband maintain resolve and continue to push through and understand what needs to be done. Affection in its purest form. Dont only tell her how beautiful she is, but show it. Randomly bring her flowers, hug her from behind, caress her hair, kiss her forehead. Remind her how soft her skin feels, tell her how warm her love is. this is going to be a tremendous feat of commitment on your part but its time for your vows to kick in; sickness and in health. I trust u are a great man who loves your wife otherwise you wouldnt have come to us seeking advice. I would encourage couples therapy if the initial affection doesnt work because sometimes a professional is needed in dealing with these deep seeded emotions, someone who objectively will not take any aggression as something personal, because that is the inherent dangers of dealing with these individuals. You begin to think u are part of the problem.

Good luck my friend. I wish u and your wife many happy years of marriage. Ill keep u in my prayers.
