How do you get premarital education to address the above issues?
Thankfully, you have a number of choices and can pick the one that resonates the most with you both. Whether it's premarital counseling at your church/synagogue, with a relationship therapist or a self-help book - the important thing is to get it somewhere.
If you're a "do-it-yourself" type, you might enjoy my workbook, The Premarital Counseling Workbook for Couples that specifically addresses the above issues. If you feel like your relationship is not as stable as it could be, seeing somebody face-to-face is probably a better choice to manage any challenging speed bumps that may come up.
