Why did you fall in love with your significant other?

I think the thing I love most about my guy is that he loves me so completely. He is incredebly respectful of me, he listens to me, thinks about me before he thinks of himself, puts me and my needs above his, and spends his spare time with me and his kids instead of running around with his buddies. He also seems to balance me out. I tend to be more quite and reserved where he is louder and more forward and outspoken. But also tones it down if I ask him to.
