That men after sex will say just about anything to get it, no matter how untrue it is, including "you are my friend above all else"

Or it could be that the way they feel towards you changed after having sex. It happens. Relationship dynamics change.
That there is no happily ever after.
And there shouldn't be. What a boring ending.
That yes the only love I would ever get from a man was the shit type, but that I didn't have to stay with him and that being alone is better.
A lot of people suck at relationships. I'm glad you got out of it, whatever it was.
That something was wrong with me, would have spent less time trying to be normal.
This might sound like a platitude, but there's no such thing as normal. If there was, it would be boring. I found that I started being a lot happier and "shined" more when I stopped trying to be what I thought people expected of me.
That I could be more selective with my friends, so I didn't waste time and effort on so many false friends.
The way I see it, you don't have to be close/good friends with all your friends. You can hang out with some people without taking your friendship too seriously. I think it's generally a problem with introverts that we try to get intimate with as many people as we can, but some people just can't handle it.
That there was dog shit in that grass.
When I was in Paris with my family, we were in a cab and there was dog shit all over the floor in the back. It soiled our clothes and bags. That was 17 years ago. I still remember the smell.
