I Am In An Age Gap Relationship

My man is 22 years older than I. Well, 21 years and 7 months. It's only been fairly recently that you would know there is a big difference in our ages, he's a very handsome man with a great body. His health has taken a bad turn; we can't do the things we used to do, and instead he needs a lot of help from me to do ordinary things. Some might say this is a reason not to be in a relationship with such a large age difference. Would it be better for him to be with someone his own age, who couldn't help him? I'm glad he has me.
