Over the last few months have had a relationship that has progressed from coworkers>friends>crush>dating. We have taken things slowly and are very much still in the early phases of dating. There is a lot still to learn about eachother and figure out how we interact. There is still a lot of time for something to come up that indicates we are not compatible, and I do not want to rush things, part of the magic has been how slowly and naturally this has progressed.
At the same time, I have this like gut feeling that she is "the one" or whatever. She is funny and smart and emotionally intelligent, and so far seems to share an outlook and communication style and life priorities that are compatible with mine. I am a 30 year old man, and this is far from my first relationship, I spent my early 20s doing a lot of dating and my mid-late 20s in a stable, long term, but ultimately incompatible relationship. I made a lot of mistakes over the course of the last decade, and think I know what I am looking for more clearly. None of the things prior ever felt like this, which has been a slow, (mostly) natural progression that sometimes literally leaves me dumbstruck at how wonderful the person I am getting to know is.
I guess what I am asking for advice on is how do I balance things? The cynical, realistic side of me knows that it is still way too early to know for sure, and I feel naive and goofy. On the other hand, I don't want to overthink things and focus so much on being cool and nonchalant that I forget the romance.
Also, and I realize this subreddit doesn't likely have many people who are in long term, secure relationships, but I would love to hear from someone who thought they found "the one" early on and turned out to be right.
