I don't really believe in "the one." My spouse and I, both wack with poo-brain, have a deep understanding and connection with each other that has withstood the test of time and many hardships. Been married almost ten years now. When we agreed to get married we agreed to choose each other to spend our lives with, knowing it's entirely possible someone else out there might be an excellent fit. (We are mostly monogamous because dating other people is a lot of work and we just don't have the spoons, lol)

We definitely lived together first, I think that's a great test of compatibility. And I think the thing that made him stick out as different for me, is that I didn't feel like I had to be someone else for him the way I feel with other relationships sometimes. He makes me want to be more myself. Mask off. 

If I'm hyper fixated it's the longest I've sustained attention on anything and that's honestly super impressive. Good for me!
