How to get out of a forceful and abusive friend group

(Age 14)

I'm trying to get out of this friend group of 4 but not because of all of them, the friend group of 4 is kinda also split into 2, so theres 2 duos but that only started to happen overtime but dont get it wrong its mostly us 4 together, but me and my other friend have been getting way to much abused by them like im talking abt bleeding (unlikely but happens), swelling, sores, and much more and this isn't from them beating us up, its because they randomy do stuff "as teasing" us and its not good, we also play soccer and the other 2 foul so much, to everyone and I got so badly injured because of them, but they like dont care. And the lust they have is at insane levels, I couldn't tell you. But the thing is, why can't I separate from them is because of the connection of the family, all 4 of our families know each other and have had hangouts (not that much). They also compare me to them (so if I try to break away from them, my family will say you should stay with them so you can learn from them) when in reality, they only do that in front of my family. They lie so much, and they never tell me secrets, so at this point, it's not even a friend group. And now we barely have anything in common. But yet they still come to my house to pick me up with a smile on their face and ask so kindly and greet my parents, and I can't even say no because they know I'm free and my parents tell me to go to (because my parents are friends with them) and by the way all of the bad stuff listed in here is only because of the other 2 out of the friend group of 4. Any help to get out of this??
