As long as both people are adult age shouldn't make any difference. My mom married a man 14 years younger than her and was very happy. My sister married a man 22 years older than her and has been happy for just over 30 years so far.
I married a woman a few years older than me and we fought about everything. After almost 25 years we divorced and I spend several years on my old. Now I am engaged to a woman almost 30 years younger than I am and have never been happier. We are best friends that are able to talk to each other about anything, enjoy the same things, and have the same political/religious beliefs.
