My question is: should I end my 8 year long relationship with my boyfriend for a new relationship with someone else?

I am age 57, mentally disabled just looking to answer and ask questions, I live on the East Coast of the United States of America I try to give positive advice and keep things for real and I expect the same treatment in return have a Blessed day hope God Blesses your day with the best of health, happiness, Many Blessings.
