That's all fine and good that you want to be a wonderful, loving H. I am saying that it is her emotional addiction to these other men that is causing her to pull away from you. You could be the grandest H on earth........and if she is involved emotionally with any other man, it will have huge affects on her feelings about you.
Many H's would stake their life on the W not having another person involved........and say they felt it in their heart, or their W wasn't the type, was a good Christian, and many more reasons..........only to discover she was cheating. For all I know, you do not consider her activity with these male contacts as cheating. I can speak from experience and tell you to take it extremely serious. Do not sweep things under the rug, or turn a blind eye.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
