Saddened

I have been married for 25 years and have a wonderful husband (more like a 
live in mate), but I don't feel any emotion.  We haven't had *** in about
2 
years and I fell like a zombie at times just going through the emotions of

staying together because of what we have.  We are not strapped for money
nor 
do I have any restraints on spending....within our needs and budget of 
course.  How do we get back the spark we had so many years ago after it's 
been so long?
