Long Time Married Men Who Are In A Roommate Phase Of The Marriage, How Do You Handle It & What Advice Can You Offer?

I (57m) have been married for over 25 years & for a variety of reasons the relationship part of the marriage has deteriorated to that of us being roommates. Pretty much the only thing we do together is have morning coffee together since I work from home. Other than that, we don’t go on vacations together, we do family functions separately & there is no intimacy because one of our kids is home from school but will be returning to school in August. We do share certain household chores such as cleaning, food shopping, cooking but since she (62f) started collecting social security, she stopped contributing financially to household expenses. I’m wondering if there are any men out there who are living as I am and how you handle it. Do you have any advice?
