Slim iPhone 5 case that works with a Glass Screen Protector?

I've been doing as much research as possible online to find a case that'll work with my iphone 5. I have a glass screen protector that goes edge-to-edge, so i have some criteria:

- Little to No lip (because the glass screen protector is edge-to-edge)
- Slim
- Something that covers the top AND bottom, not just the sides. Many slim cases lack in this.

And these would be nice, though not imperative:
- Black, matte
- Buttons covered

I've checked out many brands and the best one I've found is the Slight 5 by Desmay. I'm just trying to find something with a lower price tag. BIG NAME BRANDS NOT REQUIRED!

I hit my husband after months of abuse. Am I crazy?

I got married one year ago.

About 4 months into the marriage, my husband became extremely psychologically abusive and controlling, as well as physically threatening on a few occasions.

At that point, I was despondent and felt I was losing my mind. I decided to leave and go to a shelter, it was that bad.

While I was packing my bags, my husband kept trying to obstruct me by taking stuff out of the bag every time I would turn my back, hiding my things (phone, medication, etc) when I wasn't looking, or blocking the doorway. This went on for almost two hours, with him taunting me the entire time about how "stupid" and "crazy" I'm for wanting to go to a shelter, when I could be "safe" with him…

I told him to stay away and warned him that if he crossed over to my side of the room again, I would call the police.

When I turned my back to get some clothes, he came over and took my phone out of my bag…

At that point I snapped and went nuts, I took my purse and started hitting him as hard as I could with it until he backed into the corner, screaming and yelling that I was going to kill him if he came anywhere near me again… I wanted to scare him and make him realize that I'm capable of defending myself.

Well, he had turned his iPhone on and secretly recorded the entire thing---minus the two hours that he had been taunting and harassing me and blocking the doorway.

Now that I have a restraining order on him and we're getting a divorce, he keeps playing the video to anyone that will watch it--police, psychiatrist, court, etc…

I know violence is not okay, but I don't think I'm generally crazy or have a bad temper.

Am I mentally ill or is what I did understandable given the circumstances?
