<human>: It is a horrible thing to lose someone you love. My ex broke up with me about a month ago. She sited commitment issues, saying that she need to grow up and she was not ready for a serious relationship.

I totally understood her reasons and let her go, but I feel so hurt. Didn't anything we have mean to her? She broke up with me during finals in the parking lot of the local JC. 

I saw her the other day, and she was just so happy. It killed me to see her like that, as if she's moved on from me already. She very well may have, but what does that say about me? I feel absolutely destroyed.

We met families, talked about problems, and worked through everything we could. But now I see her posts once in a while, and my heart is just rent in two. She looks happy. Like, just like that I'm out of her life and everything is fine and dandy.

I have been no contact since it happened. I have done my best to avoid any and all mention of her. But sometimes things slip through and I see something. And you know what? She is happy.

As much as I hate to say it, I'm glad for her. She is a fantastic person, and I really do wish the best for her. But I still feel like there is something there for her in my heart.

As long as I feel that, I will not attempt to contact her. Even though I still miss her more than anything, she hurt me like this three times already. I hope she will be happy, and I know that she will be. I would like to become friends with her at some point, but I have no idea how to.

It's just that I have no idea how to be happy myself. Life seems boring now. My friends were her mutual friends, so I can't really talk to them anymore. My other friends are spread across the world. I am alone now, for the first time in a long time. I have a job to keep me busy, and a good family that takes care of me. But how do I find that spark that made me happy with myself?

Can you give me the gist of the text in a nutshell?
