One day when I got home my dog was missing.
Does your dog run away from home often?
He ran away from home a couple of times in a year.
Apparently your dog is not happy with you. It's your responsibility to take good care of him. No wonder he runs away.
I don't even really like the dog. Sometimes, I don't feel like walking it and I wish that I never got it.
If you don't want the dog, you need to find a good home for it. But, you still need to take care of it until that time. You made a commitment to the animal and it relies on you.
