I understand this one all too well. The Narcissist/Sociopath doesn't feel the need to be present in the marriage/relationship. While you are left to raise the children, work, maintain the home & cater to his/her every demand, he/she is out having their good time and concerned only about his/her self. Your needs and desires come only after his/hers has been met......if then.
Dear Husbands, I ve heard from your wife---she needs your attention. She tells me she s lonely. She feels isolated and ignored. Her life is wrapped around children, work, and/or household chores. She used to feel in love with life, and in love with you, but now she feels worthless and uninteresting. She feels like she s forgotten how to have fun.
This is powerful to me because it is so true. NEVER stop engaging in stimulating conversations with your spouse. FOCUS on your life together. NEVER let your own selfish, lazy needs get in the way of that. When lonely enough, even THE BEST spouses can become intrigued by someone paying attention to them and their needs. Others wonder "how did it happen? I never saw that coming". This is how. C.
