The truth is, there is no "right" way that works for everyone universally.
Generally speaking, though, make sure you have discussed how your life will be together. If you haven't talked about all the details you can think of, you may have a rough time of it, whether or not your marriage survives.
My opinion of marriage keeps changing as I get older. Been married 18 years and am happier than I've ever been. We get along great with each other. At the beginning, though, there were some tough times but we hung together and it's working like a well-oiled machine now. I'm no longer a conceited bastard and she's not a ***** any more!
I highly recommend pre-marital counseling. We did that after a fashion and it helped us immensely. Have some agreements up front before you take the plunge. Agree on how you're going to deal with conflicts and disagreements. Etc. etc. If you do, you have a way to get through them when or if they arise.
While I did say that there is no "right" way to make a decision, there are some generalities that I always suggest. Both of you should have dated others before you marry. Both of you should be well-established in your career first. You should both be ready to have kids. You should live with each other kidless for at least a couple years if not four or five years. I think that's about it.
If you need a rationale for any of the above, I'm more than happy to discuss it. I love to hear of successful happy relationships and hate hearing about breakups which can be avoided early on.
Best of luck to you, whatever you decide to do. Whatever you do, stick to your guns once you've decided how you want to proceed. Last but not least, she rules the womb. If she decides to have a kid, you're out of the loop so if she starts pressuring you, be careful where you plant the seed!!
