Congrat's ptangptang! I'm 65 & my wife & I been married for many years. One specific piece of advice I would offer is to keep you finances separate. Assuming that you both have separate sources of income, from whatever source, have separate checking accounts or whatever you use. Many arguments among couples start with finances. If you have your accounts & she has hers & you split the expenses 50 / 50, or whatever percentage arrangement you have, then it's much easier to avoid arguments over money. You know how much money you have & what your portion of the expenses is. And, likewise, she has hers. Then whatever each of you has left over is what you have available to spend on luxuries, either separately or together.
