Does everyone deserve a second chance?

This guy messaged and called me last night, and I feel indifferent about it. It used to make me so excited when my phone would light up and I would smile at the sight of a message from him, but now he's broken my heart and I've allowed my feelings for him to die.

Yesterday I made a spur of the moment decision to take a train to another city. Kind of a mini Eat, Pray, Love moment, I guess. Lol. And I've been having the time of my life. I strolled through the streets, did a little shopping, and tried different food from the food trucks I passed by. Even went to an open mike poetry slam last night... and then he called. I hadn't even noticed I missed his call until I pulled out my phone to find directions to the club I was heading to.

I wanted to talk to him, but I shouldn't, right? If someone isn't there for you the first time around, can that change in a week? Or would things just be the same? Also, the hurt that he made me feel makes me think that I'll never be able to feel the same way about him again. It requires a level of trust that I don't think I can give him.

I'm trying to not repeat old patterns.
