I have decided. I'm absolutely positive about this. Please correct me if I'm wrong.
A couple has to love each other equally to be able to have a lasting relationship that is worth anything.
I've realized that more than 90% of my long lasting relationships (which aren't many) haven't been totally balanced. There is usually one person involved who is "more in love" than the other. Sometimes it's me, sometimes it's him.
I'm coming to realize that a true "soul mate" is someone you love unconditionally and who loves you unconditionally. I also know that it is a pretty rare thing to find.
To be honest. I don't know what I have now. I'm guessing that there's a kind of equality because it has lasted so long. I think it may just be out of habit or we're just used to each other. There's love but it's not that passionate unconditional love.
A psychologist once told me that "the man you marry isn't always the one you love passionately". That just sounds sad to me.
