How involved should I be with raising my girlfriend's child?

Move out...I doubt you are both ready for a live in situation...you hardly know her...u have been together for less than a year.Do u really want to take the responsibility of this kid? Do u really want to be the door mat for your girlfriend? this isnt gonna change, can u put up with it for the next 20 years? take some time to think about what you want for the rest of your life.
