Woah, 24 years sure is quite a gap.
I prefer older man too, I don't know, they make me feel safe because they are wiser and taller than me (?) LOL But, I've never considered an age gap beyond 10 years, for myself anyways. I guess some people just stick to the conventional and can't understand everyone's personal feelings and point of view. I don't quite get it but if you say your love is true, and he already married you it means he loves you deeply too! And I don't think people have right to stomp over your feelings and make you feel bad just because what you picked for your future is not traditional. However, in my humble opinion, I'm more worried about the biological part of the relationship, as in if you have considered that your husband is probably going to die before you? Or, all the care he might need as he grows, significantly, older than you?
I do wish you both all the happiness of the world, because true love is such a rare thing to find nowadays
