Ignoring the age gap, I would advise any 22yo woman to wait for marriage. As many have said, there is a big difference between 22 and 27, less between 32 and 37.
Get going on your career/work history, build up a solid CV, do the training and degrees and you need.
Assuming that you will get married anyway - If you want children soon, then with that age gap, I would also advise that he organises a sabbatical to take care of any babies while you go back to work - he will have much greater job security while you will still be fairly junior. You would have to budget carefully together to make that work, be willing to use childcare at a fairly young age, and truly value your working life.
But really that's me advising young me. Not everyone is career-focussed and that's fine. Plenty of women take 10 years out to raise the dc then go back. This often tanks their earning potential and slows or in some cases stalls their career progression (not always!), but to be honest raising dc is great in and of itself if that is a life goal for you.
It does depend on who he is, true, but mostly it depends on you knowing yourself very very well. So that your goals and wants do not get railroaded by an older man's established life. Not that he'd do that maliciously, it could just happen.
