If there's anything I have learned about dating, it is that a lot of what makes it work or not is scientific. Chemistry.
I believe chemistry plays a role-a huge role in all relationships. Chemistry between co-workers makes employment more enjoyable. Friendships are dictated by chemistry. Also, romantic relationships are dependent on the chemistry between two people. Like on of my favorite Bush songs says it is all about "chemicals between us."
You can't fake or buy chemistry. It either exists or it doesn't. You're either attracted to someone or you are not. It's always difficult for me to tell someone I know is interested in me that I am not interested in them. You never want to hurt anyone's feelings because it is not personal it is...well, chemical.
I will admit that relationships are much more complicated than just science. There's also life-people's situations (finances, family life, health, mental state, etc) can sometimes get in the way. Additonally, everyone has standards and deal breakers. The older I get the more my standards evolve. For example, (and I know some of you will shake your heads and fingers at me) I would prefer to marry, if I ever marry, a man who doesn't have children. If I ever decide to bring kids into the world I would like it to be a new experience for us both. I think that'd make it more beautiful. It's funny how time changes people. It changes me. It's weird. The old me never thought about a family. For anyone that knows me they know that I don't really think about that kind of stuff. But, that's the way I feel lately-sometimes. Of course, none of this will ever happen without the right chemicals.
