B”H Liora that this is the only thing bothering you and should stay the same.
There is an old Yiddish saying which i will write in English,”that so long a person lives with a peasant till he himself becomes a peasant”, meaning when one lives with someone long enough, he becomes like the other person, which sometimes means looks too.
For a reason i will not reveal, whenever we fly to E”Y, we have an acquaintance who feels Hakoras Hatov for a favor and sends someone private to pick us up. The private drivers never fail to know who we are, without even having seen a picture of us! It’s the way we are described that helps.
Even in such as a hospital setting when one was looking for the other in a certain area, the worker would say “you are looking for so and so”!
So Mazel Tov and continue growing together and understanding each other for the good only! And remember no one is perfect!!
And of course remember the mitzvah of Kibud Av V’Aim!
