Questions to ask before marriage?

I know that marriage is generally looked down upon by TRP. You need to be absolutely certain because it is forever.

For me and my values, I see myself getting married some day, simply because I want the challenge of raising a child. I think it's one of the most rewarding experiences in life, from what I can tell, and it is, after all, my biological imperative.

I believe that the optimal setting for raising a child is in a one-man-one-woman household, sealed by marriage. That is the best way to accomplish the goal and receive the reward, again, in my opinion.

Maybe that opinion is wrong, and if you think so, feel free to challenge it, but I wanted to ask some questions under the assumption that this opinion is generally more or less correct.

I may have found the one. She has a very strong, supportive family, with absolutely no history of divorce within branches and generations of the family tree. Her father figure is strong, the leader of the house, and there is good dynamic between he and his wife, from what I've seen in the 4 years I've dated his daughter. She is beautiful, and we get along without any major fights. A lot of "TRP material" check-boxes are marked.

There are some things we don't see eye to eye on, like for example, if I want to smoke weed with my cousin once in a blue moon, she gets very hurt (her grandfather died before she was born from lung cancer, and so she has a strong aversion to any form of smoking); also, she does not give blowjobs, and this bums me out, but I don't believe it should be a game breaker; and she can be emotional about little things - but what girl isn't?

What are some questions I should be asking myself? Asking her? What do I need to absolutely confirm before making a commitment? I believe in TRP. It starts with the premise that men and women are fundamentally different in the way they think and the way they are wired. There is no such thing as true gender equality, and any efforts to equalize the sexes - not in terms of legal rights, but in terms of roles/responsibilities and motivations - are flawed. I know what it's about, and I accept it.

I'm seeking advice from close friends and family, but it's important for me to look at the situation from this perspective, or through this lens, as well, because I won't get it from my mother, or from friends who are betas. All of the input I'm seeking will be weighed against eachother, but I need this perspective because I see definite value in it.
