Why do parents do what they do?

Years ago, I used to date someone not having the same religious faith as mine. He was a Christian. Our relationship went for about 2-3 years, and went to be one of the most painful relationships I ever endured.

There I was, being a teenager very much in love. I could never get what was so wrong about my relationship. I was only 18 at the time, he was 24. My parents went berserk when they knew about us, so I spent those 3 years full of cold wars (and hot ones) with my parents. Just yesterday one of my bestfriends told me that when she had lunch with my mum (don't ask why), my mum told me that she actually liked my ex. He was really handsome with a very athletic body, he was smart, he was really nice, so she actually approved the guy. Obviously except for his religion.

What I couldn't get was, why did she do that? After 8 years, she chooses now to admit that she liked the guy. At that time, whoa.. It was as if I dated a midget. So why do parents do that? I suppose it would be a lot easier for me to accept, if at that point she told me "Hey. I get how you feel. He's amazing & all that, but at some point your relationship isn't going to work, so why wasting your time?"

Had she said that, things would've made more sense. At least better than "Nooooo.. He's eeeeevil. Stay away from him!" Obviously it only made me hanging on to him even more because I couldn't see what was wrong.

I think parents should understand that their kids grow. And that when their kids grow older, they use their logics too. They're not human beings who are made of emotions instead of logic and incapable of making a good call.

But heck, what do I know. I'm not a parent yet.
