This is very dangerous. I can't involve you in this.
It's not like it has nothing to do with me. I'd like to be a source of strength for you.
この場合、次のような言い方ができますよ。
ーThis is very dangerous. I can't involve you in this.
「これは本当に危険だから、あなたを巻き込むことはできないの」
to involve someone in ... で「人を…に巻き込む」
I can't let you get sucked into this. で「あなたを巻き込むわけにはいかないの」とも言えます。
ーIt's not like it has nothing to do with me. I'd like to be a source of strength for you.
「私に関係ないことなんてない。あなたの力になりたいの」
