Friend's mom called me a bad influence?

so basically like a week ago, my dad walked out on me. So i decided, to walk out to. I was sick of my family - and I called my best friend and she said I could sleep at hers for that night. So we went to her grans house and we told her that.my family was out and I needed to sleep somewhere. Anyway, so it ended up I couldn't sleep there and my friend walked me to the busstop - I was gonna sleep rough. But then she was like "I'm coming with you, we can run away together" I told her to go home - but she pestered, so I just said fine - it was her choice. So we stayed at this playground until like 10pm, and then we got a phonecall, begging us to come home, from our friend. That the police were out looking for us. So we grudginhly went home and got screamed at by her gran, her mum just sat there quietly. So now, its been a week. My best friend is blanking me - and its not cos I got her into trouble.. Its cos her mum told her she couldn't talk to me. she even deleted me off bbm..i'm a bad influence. I have no idea what to do, will this carry on forever? How do I get her to talk to me again? I'm a year older than my friend.. I didn't want her to come, but I couldn't force her to go home right? What do I do? Help..x
