I get lucky if we have sex once or twice a month... Yep it's bad. Bust on my wife?? Watch what you say, karmas not pretty. Kaniff
I am going to suggest a little more reading for you.
MW Davis the Sex Starved Marriage. (She also recommends Getting a Life, and explaining your needs, becoming less clingy) It is a good companion book for a man in a Sex Starved Marriage.
Chapman's The 5 Languages of Love. This book is usually found in the religious section of many book stores. That was a surprise because it is not a religious book, but it is used by many church family counseling groups.
What I learned from Chapman, was that my primary love languages were "touch" and "words of affirmation (praise)." My wife's primary love languages were "acts of service" and "quality time."
My wife and I drifted apart As the mother of two young children she was touched out at the end of the day and the last thing she wanted to do was touch me. I didn't feel loved. She also was too tired to really praise me even when I went out of my way to solve problems for her.
Each day as busy as she was she made a homemade hot dinner. That was her primary act of service to say how much she loved me. To me it was just a meal. She felt I didn't love her.
Since I wasn't feeling loved at home, I started working more hours to get promoted and be a better provider, or so I told myself. It was actually to get praise from coworkers and my boss. If I worked late and didn't call her and the dinner burned, she was very angry. It was like she had said I love you in her love language and I had slapped her emotionally. She would sometimes yell at me for being late and ruining dinner. I would try to avoid conflict by leaving the table and watching TV or playing with the kids. That would infuriate her even more as dinner was suppose to be quality time in her mind. I was doubly making her feel unloved.
I thought I was being a good provider and getting yelled at for it. She felt I didn't love her any more. If I touched her to tell her I loved her in my love language she told me I was pawing at her. If I praised her to tell her I loved her in my love language, she told me I was buttering her up to get in her panties. If you say to someone I love you and their actions say they don't want your love, you feel very unloved.
We drifted apart like this for years until we had a pretty classic sex starved marriage. Neither of us realized that almost each day or at least several times a week we reached out in our "love languages" to the other only not to be heard and sometimes to be rebuked.
In your first post, you talked about marriage counseling. I would suggest that, but with a board certified sex therapist. I would also suggest you do some serious reading prior to your first sessions and figure out how you are going to change yourself. You can not expect to change her as only she can change herself. You can show her that change is possible. You can further change the dynamic in your relationship (read MW Davis SSM on the art of the 180), so that she will have to figure out if she can still treat you the same or if she needs to change how she treats you. You many like the changed way she treats you, but if you do, provide lots of positive reinforcement.
It took a long time for me to figure out what I had done to hurt my wife and to change the way I treated her, so she started to feel loved again. It also took about 5 months of therapy with a nationally known sex therapist to heal our relationship. But even as expensive as the ST was, it was far less than we would have spent on two divorce attorneys and that ultimately was where things were headed.
Good luck to you.
