I understand why you feel like this is something yours and it isn't fair that you already got screwed by being born trans and having to take hormones and get at least one surgery done to finally be yourself on the outside.
But at the same time I personally think that there are 2 people in a relationship, and ignoring how one feels about what the other is just isn't nice(even if he has preconceived ideas of trans people and doesn't want to understand us)... not just that, but if he were to ever find out about you he'd feel betrayed, played, as if the whole relationship and marriage were a lie, a passing game to you, a "let's see how long I can fool this stupid guy" game. We understand you, I understand you, but will he? after years of marriage?

Also, is it worth living hiding a secret at all costs? Be sure to marry someone who you can feel comfortable with and that they know that what they get is what you are. Being trans is, fortunately or not, part of who we are.... if he finds this out himself things might go reeeeally bad.

whichever way you go make sure you'll be happy in the end and safe
good luck ^___^
