You're so young you don't realise how far you have ahead of you and how easily you can make a new life apart from what little you've lived to date.

Don't sign up for a lifetime of this. Just don't. You're so young, you can get free without losing a family, home or finances. Go and don't look back.

I know you probably won't listen because everyone thinks they're unique and that the experiences of those that have gone before won't apply to them for some reason. But I'm going to tell you anyway just in case you can listen. Her behaviour is deceitful and unreliable. Don't build a life on that sort of foundation, because it doesn't lead to happiness. Be brave and let this girl go and find one who will not be an anchor around your neck costing you happiness and mental health.
