So I made a list, and the pros are fairly obvious to me. Good, kind-hearted person, similar values, I can trust her, attractive, concern for others, intelligence, similar goals, similar views on children, money, and she even likes to watch the game with me.
Cons are the feeling that something is missing in my life. She doesn't really add or subtract from that, so I don't know if that is even something to look for. Other cons include her stubbornness, a certain clinginess, and her family history, which does not include any happy marriages and instead a lot of painful divorce.
One of the other posters hit on something about love. It is something deep that wells up inside of you, beyond a feeling of butterflies. Maybe this is what I am missing. I feel compassion and concern for her, I want the best for her, but I guess when I am really serious with myself, I don't have this huge fountain of emotion inside of me for her. I don't find myself thinking about her all the time. I want to, I try to, but it does not come naturally in this relationship. I can see though that at her essense, God made something really special. Her presense in a room or crowd just feels good. I still don't know where that leaves me.
