When you get married, certain things get better, some stay the same, others, well ... um ... definitely don't get better. Things that barely scratch your annoyance meter now ... rarely recede.
Marriage is many things, but ultimately it is a partnership. Being as like-minded as possible sure helps.
Two things I advise my sons:
1. Look at her mother, that's what she'll probably end up looking like.
2. Look at her relationship with her father, that's the default model for her relationship with you until several years elapse for any reprogramming of the actual mechanics.
Ultimately, if conservatism and/or prepping are a lower priority to you, which is to say, you could / would [back-burner to drop] them for the sake of your love for her, then accept that now. It will be much harder later. On both of you.
If you can't back-burner or drop those things, it's easy for me to say, but you'll both probably be better off not as a permanent item.
That's what I would tell my own sons, anyway. FWIW, YMMV, and all that.
