Letting Off Steam

I have days where I am sad, angry, hurt. I think about him and I just wanna smack him! I don't blame everything on him, even when I want to.
The thing is this. I hate how he can just walk away and forget about it.It hurts how he told me to get rid of it. Just because he doesn't want it, just because he thinks it is messing up his whole life, doesn't mean it isn't his.
I think, in a way, I am jealous. I'm jealous that he has the freedom to do what ever he wants and take no responsibility. That he can just pretend like nothing happened and continue with his life-everything as it was.
I hate that he gets to be so damn happy with his perfect skinny girlfriend. I hate that I'm hurt and to be honest I just hate that he can get away with this while I can't.
So here i am ranting and raving-letting off steam.
