I'll try to be as gentle as possible with my answer although I was the LBS.
My X "needed" me to provide a lifestyle, she "needed" the resources I provided, she "needed" a babysitter and a handyman, and a gardener. What I "needed" didn't matter, don't bother her with it. Its all about me, do for me, me, me, me, take. take, take. Don't even ask to have your your needs met.
As a generality when a man says his needs aren't being met, the emotional and intimacy needs have been unmet for extended periods of time., possibly even years.
Quite often men stop asking because they are tired of excuses and that everything and everyone are more important than their needs.
Part of the difficulty in moving on is the realization that you did play a role in your partner's descent, no you are not responsible, but few are ever truly guilt free.
