My 18 year old little sister found out she is 2 months pregnant,?

Thats what happened to my cousin, she was in love with this guy who was 6 years older then her, she was still living with her parents n going to school. NOONE liked him, he was a sbag. She kepted the baby, but her parents and sister mostly take care of it for her. he only see's the baby like once every 2 weeks. You need to think whats better for the baby, you need a good stable home for that child, if she can give her baby that n know for a fact that her bf isnt gunna leave her or not take care of his family then she could keep it.
