I have cheated on every person I've been in a relationship with.
That's insane, why have you cheated on every single relationship you've had?
I get bored of them.
You shouldn't cheat on your partner. That is very wrong. You need some help with that.
You should mind your own business.
If you really do not want to talk about it, then I will stop, but let me say this: cheating is morally wrong and you've hurt the feelings of every single one of your relationships. You will be actively avoided by people in the future if you have this reputation and you will end up not having someone that would really be in love with you because they are afraid that you will cheat.
