He doesn't love me enough

Recently I found a blog. The author likes to talk about relationships, kind of like sex and the city. Today I read one of her articles, she talks about some of her friends, they probably have been with their boyfriends for several years, but their boyfriends don't want to get married. When they finally broke up with them, for some reason the guys get married with the new girl friend within half year.
How wierd! They don't want to get married and now they get married that soon after they broke up with old girl friend?
The conclusion is clear, he doesn't love you enough.
After I broke up with my ex-boyfriend, this question really confused me for a long time. Am I not good enough? Am I too pushy? What is wrong with me for him not wanting to get married? For a long time, I always think its his problem, oh no his parents' problem. I always think his parents educate him the wrong way makes him so scared of commitment. So I kind of hoping he will never get married then one day his parents will realize they were wrong at the beginning and apologize to me..hahahah. I am mean.
But after reading the article, yeah its all clear now. He doesn't love me enough. It might seems like he loves me, but probably because I love him too much and I don't realize he doesn't love me as much as I do. And I thought I understand him, I thought he is the best guy I can meet, but thats what I thought when I was in love. Now its all clear. No, he is not the best guy, he doesn't have a clear idea where he is going. His thoughts always change after he talked to someone. If I am still with him, I will still be in the pain of the uncertainty for life.
Too bad this question still bothers me after I broke up with him a year ago. Maybe first relationship is always painful. Although I barely think of him, but sometimes I still wonder. I guess I think too much. Stop thinking stop thinking!
