Mazel tov! Congratulations! Happy day ;-)
Finding the right person makes all the difference - I can tell you from hard won experience! So sure, count me in to celebrate your good fortune ;-) I wish you both much happiness and joy!
I was traveling and didn't have much time to write any words of wisdom so here goes;
Marriage may be a lifetime commitment but if you look at it as a daily commitment it takes on a whole different light. Each day brings different things - sickness, joy, dullness, exquisite happiness - but if you commit to being nice to each other no matter what each day brings, you'll have a marriage others will always envy and well you'll be pretty happy too!
http://www.webmd.com/sex-relationships/features/happy-marriage-no-nitpicking It is easy to forget the little things as time passes...so try to make a few things special like always holding her hand when you walk in public or kissing her on the forehead when you part ways - if you do one or two small things that connect you physically every day it becomes a habit and it makes it much more difficult to grow apart or even stay angry at each other for very long.
Help out around the house - srsly, most women still feel like it is their job to do the housework so find something that isn't terribly onerous and make it your job - dishes, laundry, mopping the floors - even one thing done regularly will make her feel like you two are a team.
Listen.
Share what's going on with you.
Make her laugh on a regular basis. Even if you are not naturally funny, find something on the internet or in a book. A man that makes an effort to make a woman laugh is a joy indeed ;-)
Lastly, don't let sex become the last thing on your "to-do" list. Make a commitment to a physical relationship because there is something amazing about how it creates and maintains a relationship.
