Petty/selfish husband

My husband has always been a petty and sometimes very selfish man. For instance, I forgot my hat in his truck one evening and to this day, I have no idea what happened to it, he keeps saying I shouldn't have left it in his car but he's not telling where he put it. If I leave anything or the kids leave toys or anything on his side of the room, he'd take everything and dump it on my side, either on the bed or my nightstand and say, you're the reason they're playing in our room, so why should I deal with their mess.

Over time, just a lot of little shit like that that I've ignored or even tried to talk to him about. His pettiness has began to get under my skin though and it's a major turn off, especially today. We have a king sized bed and frame, now the frame seems a bit too big or it somehow shifted, but there's a huge gap between the headboard and the mattress. Our pillows, remotes, phones and everything are always falling under the bed. I started using a body pillow to stuff the gap. This afternoon he comes in and I'm sitting on the bed doing some research, I had our pillows stacked behind my back. Naturally he needed his if he's planning on lying down so I expected it when he started pulling them from behind me. He then moved the body pillow and kinda stuffed it in on his side, so the gap is now behind me. He lays down and goes to sleep peacefully as my pillows fall under the bed.

Honestly, at first I didn't really pay him any mind but then it hit me, he has very little respect for me and is a bit of a bully and it's affecting our marriage. We don't laugh and play around anymore because he's always being a smartass or just talking to me like I'm an idiot or like he couldn't care less how his words affect me. We've been together for 9yrs and this is the first time I've ever began to imagine life without him and I see myself free, in beautiful sunlight.

He wasn't always such a dick, he used to care about me, he used to at least try to make sure I was happy but now it's like he's trying to make me leave, like he's looking for a reason. Idk, maybe I'm just growing sensitive and need to grow thicker skin.
