Due to the large age gap, May-December romances can cause people in a society to raise their eyebrows at the relationship. The most important thing to remember is how do you feel about the relationship? There are pros and cons to this type of relationship but it really boils down to the two people involved. What are the maturity levels of each partner? What is the level of compatibility? Do you both have shared life goals with marriage, children, career, lifestyle, etc.? Is it just lust and a good time or
is it something you want to last for the rest of your life? Certainly these types of age gaps will bring with them obstacles that same- aged partners will not face. However, it can also bring with it a dynamic that many enjoy. I would search within yourself to answer these questions and ask her to do the same. In the end if you are both happy, what does it matter what anyone else has to say about it?
