Why does there have to be something wrong with me or that something bad has happened to me for me to have a different opinion on love than you? I love my friends and family, I'm not saying that love doesn't exist. I've cared deeply for people I've had sexual relationships with, but I never felt that care was any different than I have for my close friends. It's a feeling I've come to naturally.
If anything "happened" to me, it was that I learned there are women that expect because I am having sex with them I will make both my needs and the needs of my close friends and family subservient to theirs. I don't think it's right. My girlfriend of two weeks isn't automatically getting my time to watch a movie over helping my oldest friend move into a new apartment (this is a real fight I had, and I had told her I was doing it in advance too). When I explain my opinions to these women, they react like you did, they see it as horrible, disgusting or pathetic, I see it as only natural. There is nothing jaded about accepting my own feelings and limitations. Quite frankly I think you should ask yourself a simple question "Do I actively seek to spend time with my exes (without sex)?", and "would I actively seek to spend time with my current partner (provided you have one) if there was no sex involved?". See how "jaded" you are.
