Trying to Make Sense Of It All

So why is it that an 18 yr old girl with no ambition, a high school education, a loser BF, get PG so easily? Is it because she didn't have a care in the world, wasn't even trying? Was it b/c she was trying to trap the guy into staying with her? Why?

And why, above all, did she probably get PG while living in my house? Is this some cruel joke? It was supposed to be me. It was supposed to be me and Rob, conceiving our child in our own home. Not some girl, who can't hold a job, and has no intention of trying to better herself.

I don't understand why things like this happen. What am I supposed to learn or gain from this experience? Is it to finally push me to the point where I have to deal with all the anger bottled up inside of me because of this whole situation? Maybe. I just don't know yet, I'll let you know if I ever figure it out.
