Not going to vote.
Even so my thoughts about.
Though I don´t have a personal experience, IMO there shoudn´t be a stygma.
People fall in love and stay in love for their own frequently misterious reasons and that´s good.
Even so and in more general terms, relationships are not always easy, age gap or not.
Compatibility IS a serious thing.
And a signigicative age gap MAY be one factor on making it even harder.
But of course, there are counterexamples.
Best wishes for you both and your mutual love.
