I didn't find this post surprising at all. I kind of expected it because you've barely written about this topic. I'm really happy that you're trying something new in this area of your life.
Marriage does feel kind of weird to me. Why would you intentionally limit yourself to one person when there is no reason to? That's like limiting yourself to one career! I can see myself heading in this direction as well. I've already been deeply in love with two people and they were both great experiences.
To search for "the one" doesn't make sense to me anymore because I've already had two of them. I look forward to reading about this and experiencing more deep relationships in my own life.
