My girlfriend and I have been together over a year and we have a 3 month old daughter. She also has two other children from a previous relationship. When we started having problems with our relationship she told me that I could have our 3 moth old because she couldn't handle 3 children. I also don't trust leaving her here because my girlfriend's brother smokes marijuana heavily, even when he's watching her other 2 children. He doesn't even go into another room he does it right in front of them. My question is, we recently had a major fight and she told me that if I wish to leave to just leave. I don't want to take my child, have her turn around and call the police, telling them I kidnapped her and lose her forever. What can I do?
