Thanks for the advice. That might be some of the problem; when I do hang out with her as a friend I don't enjoy it as much as hanging out with a regular friend. I don't enjoy her company as much as I used to, probably largely because there doesn't appear to be the "give-and-take" that you get when interacting with a friend. Honestly, if this was a woman I just met and had went on several dates with I don't think I'd be calling her for more. But I'll keep an open mind and see how things go.
Perhaps as Bruce pointed out it's just disappointment over unrealized expectations. On the other hand, who doesn't have that? If I went on a date and I expected decent conversation and that I wouldn't be criticized by my date and it was uncomfortable silence and perjorative comments all the time, I think I would be disappointed by my date. At the root of the matter is that most of us our divorced because the marriage didn't live up to expectations.
Gabe, no one has been going down. That's part of the problem.
