Boyfrieng and girlfriend

Hi One of my friend. Who is girl. She is so close to me like a gf. Yesterday she leave her house. In evening till she has not came home return Than her family member start call to her all friend including me. Than they blame me that she may with you or else you call her anywhere. However she was not with me. On the same day i was going to kolkata by train Suddenly around 8pm a call came from unknown number. The call was of this girl whome ran from the house. I ask to her that now where is she? She told me that now she is in durgapur railway station. She ask me directly that are you coming or not. Please come early i am waiting Than i told her ok i am coming. One of Cvpf guy caught her. She called from his mobile also. The guy told me that please come early and took her. Than i call to her family member ( Mom) and told them all that now she is there and all. She is calling me durgapur. So i am going there. Kindly you all come ASAP. Around 10pm i reached there. And after that her family member came. After reacing me approx 15minutes later. His father caught me and blame me that he took my daughter and his mother and all member are blaming me that i took her daughter and all. All is my planing. But the real reason to leaving home for this girl was family problme litle fight with elder sister and some litle family prblm that why she leave the home. As she told me. Her mom also told me starting when she call me around 4pm that now she is little bit disturbed by her mentaly condition also. In reality also that is the main reason that she is disturbed by mentaly that why she do this. So now what should i do. Like the girl leave home alone by her own decision. But all family member are blaming me because i talk with her on whatsapp and call also. So what precation i should take? If in future the girl do same activity because of her family trouble. And again they people are blaming me so to prevent this situtaion what precaution i should take to avoid to come in this situation.
