Congratulations.
Some thoughts from someone who has been married six years:
1. Romantic love is bullshittake. It goes away. Real love comes later when lustful feelings have died down. But you've been with her for a long time, and should you should already be there.
2. It is hard. No simpler way to explain it than that. If you are not willing to actively kill the self you were before you got married, then don't. Being successful in marriage is more than compromise. It is giving up things that you are holding onto that you don't need.
3. Being committed to the marriage instead of your moods is critical. Many times in an argument or fight, you will be tempted to hurt the other with below-the-belt remarks. Don't do it. Be committed to the marriage and not to your feelings or hers.
4. Be ready to weather some storms. Women are unique and different from us. Don't take everything she says in anger at face value. If you do, you'll be a nervous wreck.
5. Know yourself. Know the root causes of your problems and your insecurities. There are many things your wife will do that will annoy you, but you later realize that it annoys you because of other reasons. Don't take out your anger on her. Learn to accept responsibility for your emotions and feelings. Don't act out on feeling towards here.
6. Be two individuals. You are not one person, you don't complete each other, you are not some p*ssified version of what you see on TV. Be together, but also be apart and relish in your own space.
7. Make her a priority in your life and treat her better than you treat others. She is not your buddy or bro that you can take for granted and treat with indifference. Honor her for who she is.
8. Be prepared to realize that you have married a crazy person. All people are crazy in their own way. You won't see it initially, but there are things that she will do that will drive you crazy, and likewise, you will drive her crazy. This is normal.
9. Fight. Don't hold things in and let it fester. Fight it out. Talk it out. Communicate and listen. Learn to kill your ego and grow up.
10. Realize that if you are not working, suffering, or growing, then you are not truly loving her.
11. Don't ever cheat on her. Period.
12. Be a real man. The men you see on most TV sitcoms are not real men. They are womenzied versions of what women think they want a real man to be. Being a real man, more than anything, is taking responsibilitiy for your actions. It is not about acting like a p*ssy and fawning over women and their greatness. It is treating her with respect, but also treating yourself with respect.
