How cool! Did you find yourself ever doubting the relationship once the initial honeymoon stage wore off?
I was infatuated with my husband for about 6 months, and then had a week long period when I contemplated calling things off, simply because I'd come off cloud 9 and was overanalyzing. I'm so thankful I didn't, but once the initial crushing and lovespell wore off, I had to assess the relationship once more and why it worked. I suppose time is the best indicator, and I feel we've only improved with time.
But the only way I can really process our relationship is by watching others and reflecting internally. I've currently been observing a semi-duality relationship, and while I'm envious of their extreme highs (- passion to a point that we do not have), the lows are extremely frightening. The only thing I can conclude is that duals may or may not be everyone. They're comfortable, clear, and understanding. After that initial 6 months though, I think I was doubting whether or not I wanted more of the crazymad, "let's do everything together" passion or compatible/stability, and ultimately compatible/stability was more desired. I couldn't be happier with my choice, and while we do have a bit of that passion, ours feels more consistent and stable.
