Nah. Age gaps only matter when one party is not yet an adult and free to make their own choices.

A 30 year old? If they’re not capable of deciding who to date on their own, then their conservator should say no before someone tries to set them up on a blind date.

Just make sure this lady knows there’s an age gap so she can make an informed decision. And be aware that while age gaps don’t matter in terms of who can and should date whom, doesn’t mean there aren’t extra issues that might result in incompatibilities. Those incompatibilities aren’t a sure thing either, though.
