After attempting so sort through a multitude of emotions.
Some of which I've never felt before.
I think I've figured it out.

It's okay with me if he decided I just wasn't the right girl for him.
Kudos to Collin for following that feeling - if that was the case.
It hurts if that's what he decided, but I can't blame him and wouldn't hold it against him at all.
I'm not okay with the way he's treated me since.
He has no right to treat me like crap.
Which he has.
Repeatedly.
I'm angry that he continually acts like I'm not worth the apology he owes me.
I'm hurt that he doesn't want to be in my life.
Or me apart of his.
I'm furious that he never gave me an explanation and still refuses to.
I need to have that closure and he keeps withholding it.

Conclusion.

If Collin broke up with me because he simply stopped feeling it, alright. The way he did it and the way he's been hurting me deeper and deeper ever since, not alright.
