I think as long as both sides are happy it souldn't matter the ages between the members in the couple. Everyone is capable of makeing their own dicisions and should do as they wish, after all isues like this do not harm anyone but couple itself...so y would it matter to us..i mean everyone has free will..and even if it is a mistake they will learn from the experience...but who's to say it wouldn't work out
After all far back in time 40-50 year old males would pick their wife which would be 13-20 years of age...so it could work..just..ya
