So basically his stay at home gf who cooks, cleans and takes care of his kid?

I truly hope you see you need to build your future prospects and your financial independence. This is not negotiable.

If you have your own money, you can go live in your own house away from everyone you dont want to see and create your own living environment.

If you keep on doing this, what will end up happening is that you'll have no money, no job experience and nothing to show for. If he dumps you in the future you would have to start from nothing, which will be so much harder without a college degree and at an older age.

You're only 19. Please make good decisions for your future
