craziness

My step kids have a 14yr old cousin who just found out she's 3months pregnant with her "boyfriend" who is 21 freaking years old people. I'm beyond disgusted with this, especially being and older sister of 4girls 17,15,13 &12yr/Old I thank the lord every day that my sisters have good heads on their shoulders. But anyway this little girl met this guy this past summer so imagine they haven't been together long I swear people think raising another human being is a fucking game smh My step daughter is 9yrs old and she's very close to her so I can imagine what she is thinking about this whole thing. Do you ladies think my man should sit and have a talk with her ? I mean before she's 14 and pregnant as well.
