First and foremost, I would agree with waiting to settle down later in your mid-twenties. Although, I am extremely happily married and did so when I was 21 (a year ago from December), it is hard because we are still trying to figure out what we want to do with our lives in the respect of careers, we are both in the Army and you can make your own decisions on how that may or may not help the situation and we are both either INFP or INFJ, or so I assume, and that indecisiveness factor doesn't help. In conclusion, both of you having solid career paths or knowing what you want to do (which can be hard) will help tremendously.
Second, I would also advise that you live together for awhile (5-6 months). This gives you a feel for how responsibilities will be divided between you two, because they may have a different idea of who should do what. For example, I got lucky because she can and enjoys cooking. SCORE!
But if neither of you like to cook, someone may have to learn and that is not easy and can be very demanding as small of a task as it seems. This will incorporate with it growing pains that you will have to endure and resolve.
Hope this helps and good luck!
