Okay, cheers. It still won't be enough to live on.
You don't say that your mother is a bad person, just that she's restricting you. Many parents restrict their teenagers, you're not the only one. It's a valuable life lesson to learn how to live by someone else's rules. You have to abide by rules, annoying, but a fact.
If you act mature now, accept that you get to see him twice a week, show your mother you respect her rules and can be trusted, she'll start giving you more leeway a bit at a time.
