About this boyfriend. I would contact him and his parents both, and if need be, also the police. I would make it clear this is a CHILD and he is an ADULT and that you WILL prosecute him and there is NO consent from a 14 year old with a 19 year old. Make it clear there is to be NO calls, texts, emails, messaging, in person contact, third party messages. That he is to cut ALL contact or reap what he sows. This is no joke even if the moron man thinks it is is. You have legal backing to protect your child in this situation and she clearly hasnt' any sense, and is naive as get out. NO 19 year old dates a 14 year old on a 14 year old level. PERIOD.
