Confused About Love

How do you know you're in love? Is it a feeling, the vibe of the thing, a tingling sensation? What is it?

I am confused. And I've thought about it hard. I love my ex girlfriend. She makes me happy and I enjoy being around her. I enjoy sharing things I wouldn't bother sharing with other people. More importantly I want her to be better, and I want to be a postive, supportive, nuturing influence in her life. And looking back I think overall she's been a postive influence in my life. Even the really crap hurtful times in the past, I can look back on now and can see how much I've grown from these experiences.

So I'm confused. I'm beginning to think I have to fight for this relationship. It's scarey because the relationship is over, and I feel like I'm putting myself out there and am likely to get hurt. Not a fantastic feeling. But I also feel great. I'm not going to regret letting one of the best relationships I've had go without communicating how I feel. I feel like I'm taking control of the one thing I can control. Me.

I feel like I've taken postive control of my own destiny (bit corny I know ;) and if it comes to nothing, that's life and at least I've done what I can.

Fingers crossed ;)
