<human>: Can you provide a brief rundown of the text in within 3 sentences?

So we have known eachother for a few years. We went out on a few dates, 3.5 years ago. Had a great time, but nothing came of it (she wasn't interested). 2 years ago couple more dates, great time, and then nothing (my doing that time). 

A year ago, we go on a few dates, then a few more, months go by. I drunkenly tell her I love her, another month, I soberly tell her I am in love. She replies that she loves me too. We both have quit drinking too. Neither of us were alcohalics, but we were still drinking like we were 21. And, we both just decided to stop together, btw.

Now, we are talking about moving in together, and getting engaged soon after. I have always been a serial dater (so had she), and I have never even lived with an  S.O. Niether of us ever thought we would ever get married.  So, I guess, my question is,  am I crazy,  and what are some pit falls to watch out for? How does this shit work?
<bot>: Things are moving quickly between  me an my GF. We have know each other for years but are talking about getting married after about a year of dating.
