I won't say he just wasn't that into you. (His behavior doesn't fit with any of the scenarios in the book/movie.)

I guess that since I am on the other side, I don't have any real advice. I think it is perplexing to many because they don't have an inside view, but to people like your ex and I, it is all we know. That is, this *is* our version of "normal".

The best I can liken it to is your version of love feeling like anything but to us. I realize that this is a concept that most can't even begin to wrap their heads around, but yes, when you grow up in an abusive family, "love" isn't exactly love. There are certain rules you need to follow, and "love" isn't always a safe thing or a good thing. It is oftentimes a dangerous thing. Sorry if this isn't more helpful to you, but this is how I see things as someone who grew up in an abusive household.
