been married 30 years, sure there were times when we went to bed mad, but we got over it.
Remember the bad times are usually temporary - concentrate on the good times and think, "this too shall pass." (of course this doesn't apply to abuse, alcoholism, etc. I mean temporary bad spots in an otherwise good marriage.)
You have gotten a lot of good advice so far. I would add 2 things - start off honest. A lot of newly-in-love folks agree to whatever the other likes, i.e., a wife saying, I would love to go to football games with you every weekend, when she really doesn't. Instead it is better to be honest, say, sports is not my thing but I will go with you once in a while. Otherwise you wind up 10 years later, yelling, "and another thing, I have always HATED your stupid football games!"
Conversely, when you do do something for your spouse, do it willingly and with a smile. Say you love opera and your DH hates it. It is much nicer if he takes you once in awhile with a glad heart, than if he pouts and says, "Oh ALL RIGHT, I will take you to the d*mn opera, NOW are you happy??!!" If you can't do it nicely, don't do it.
