Would you confess to your partner that you used to be a bully?

Of course u need to tell ur partner, it's a big part of ur life, there is no way u can lie about it unless u make up a completely new identity for urself. And even if u do manage to keep it secret, sooner or later things are always always discovered. There's no secret that remains a secret forever. So spare urself and him the pain, and tell him. I can tell that u havent changed much... any other person simply knows the right thing to do would be to tell.=/ Sad.
