Just go get married in the court. You may have to get an appointment based on the state you're located at. I'm sure that there must be a website that you can look into. Also, as someone said earlier, do not ask others if you should get married or not, if it is right or wrong and all that crap. Just do what you think is good for you and your future. Good thing about getting married with this girl is that she won't feel like she has been dumped even after you leave her in the future. She is playing cool and knows the outcome. Good Luck!
