Took you 7 years?! Why'd you wait so long? Jump in, the water's fine!
I shouldn't talk. My wife and I dated for 5 years before getting engaged for a total of 6 before we were married. Best thing I ever did.
Just remember your commitment you made. It's love that created or made you commit but years from now when things get tough, it will be that commitment that creates or reminds you to love each other. The "glue" of your relationship, if you will.
Blessings to you both!
