My Lady is 71 and I am 58. We have been together over eighteen years. I knew her 13 years before we started dating. We enjoy each others company and really love and care. I tell her everything, my dreams, what makes me love about her, why does she love me, etc. I trust her not to cheat, spend money and can't account for it , and in turn I do not have mistress and try to be frugal about money. Don't get me wrong, it hasn't always been a picnic. Life is all about how to handle adversity. We are a team and always support each other, when in laws try to tear and sabotage our relationship.
The chances of the 10 year marriage lasting, depends on how the couples relate with each other. How the couple feels about the age difference also maters a lot. According to reviews, most couples will last since they have known each other for long.
