I'm currently dating a girl I've known for almost 10 years now, that I used to work for/with. We had always kind of felt something for one another, but could never do anything about it due to our professional lives. We both left our jobs and have recently moved onto bigger and better things. We randomly messaged each other on Facebook at the same time a few months ago, and have been dating ever since. We truly feel we are the loves of each others life, and want to be married to each other. We definitely don't have to get married, but we want to and she wants my last name.
If you choose to never get married, that's all fine and dandy. Personally I feel it shows true commitment, love, respect, partnership and so much more. I actually plan on asking her in a few weeks after taking her out to a nice dinner.
