My husband's crazy obsession

I've been with my husband for 11 years, since I was barely even a teenager. Never been with anyone else. I can put up with alot, and don't give up easily when it comes to relationships as you can see. This time I feel like I will, and for the stupidest reason. My husband has an obsession. It's not porn, video games, facebook, or cheating. He's obsessed with his truck, and selling, trading, and buying different vehicles. He constantly ignores me. He's watching car videos or on Facebook chatting trying to trade or figure out what else he wants to do with his truck. I'm sick of it. Have hobbies, have interests, those things are what make you...YOU! But don't mistreat or ignore your SO, family, friends, the people who love you, because you have an obsession. Today it was POURING down rain, and we were riding home from town, a loud car drives by and he ROLLS THE WINDOW DOWN to listens to it.

I can't anymore.

Update: Just wrapped my arms around him and saw he was looking up car stuff online (go figure), so I tried to put him in a head lock or whatever it's called. (I grew up with all girls so I have no idea about any wrestling) I was like am I doing this right?

Him: No

Me: Well can you show me?

Him: Later, after I finish this.

I'm gonna try to talk to him once we start to lay down, but I doubt it will work.
