Once in a while he talks like a 10-year old, and is completely serious when he does. He's 25 and I'm 22, but he makes it seem like I'm dating an 18 year old. It's embarassing. He tries to joke around once in a while, but it always comes out really weird and crude. He's always tired, never wants to do anything fun or exciting, and does not like change. I've thought about leaving him more than a few times, but I really want to help him. It hasnt always been like this, he used to be really normal.
