I have a friend that's 23 years old on baby number 4. she dated a guy for about 2 months and then he left her for another woman. She is 10 weeks pregnant for the man that left her and now her and her ex is back together again. Is she stupid for keeping a baby for a man that left her and is it possible the baby can be for her ex now that he is back in the picture. Her ex and the possible father haven't met yet and she's almost 3 months pregnant. I need some advice

Really if that's the way she wants to lead HER life, what has it got to do with YOU.

Be there for her as a friend, but do NOT meddle in her life.
