Is it normal that I hate my gf's kid?

sorry, I guess I didn't really try to help you.
this is what I think and what I am doing:
- pretend to love him
- do not treat him badly or show that you do not like him
- you only have to put up with him for 4 wks per year
- that is nothing, really.
- if you love his mother, keep doing what you are doing....
- he is only 5 y/o, you might eventually learn to care for him..maybe even love him.
- good luck
