I am too set in my ways. Far too set.
I've been single since my divorce in 2005/2006. I didn't intentionally avoid it, but pursuit of my career and education was far more important to me than to pursue a relationship.
Eventually, I realized that I need not ever pursue a relationship again. I'm far too moody for most women; far too morose and misanthropic; far too distant and reserved. I'm not able to now, just as I was never able to in the past, form emotional bonds with other people. I can say "I love you", but from me, it doesn't mean a whole lot. There's no demonstration of it - no evidence. I'm not capable of getting physically close to anyone - never was. I can't - physically, emotionally, or spiritually be anything more than a very tepid friend.
There isn't any changing it. It's who I am. It's how I've always been.
If I met 'Ms. Right', I'd most likely handle the situation as I do all others - be polite but not friendly. She'd pass in and out of my life in an instant. For all I know, she probably already did many years ago and I snubbed her.
