My advice would be to suggest some quality time together, go shopping, have a coffee or a bite to eat. Things are less likely to get heated in public. And use this as an opportunity to have a proper conversation. Ask her what her concerns are and let her know you value her opinions and advice put her mind at rest that your becoming a responsible adult and make this a regular thing. It's how me and my mum changed from a parent child relationship to having a relationship built on mutual respect. I know I can talk to her about anything and am working very hard to have the same kind of relationship with my son. Good luck x
