I suppose the answers to this question depend upon how big of an age difference we're talking about.

Is the older spouse going to be able to actively participate in raising a child or children

Is there enough insurance in case something would happen

are there any valid objections from family members to the marriage

Are the two of you sexually compatible, and if not, would you mind being just companions

Is the marriage based on true love, or is it money or compassion

If either of you have children, are the older partners children going to object to their Step parent perhaps being younger than them

Do you have the ability to stick the marriage out, even if the older person should develop some major health issues

are you prepared for people's reactions when they see you together, "is that your daughter?" or "your mother looks good for her age ". The truth is people's reactions cannot hide their true feelings. The decision of course is up to no one but the two of you.

Are you going to be able to provide for your family if the older spouse cannot
