How would you feel if your partner was friends with somebody you don't like?

If you tell them that you had problems with this person and they even did shady things to you in the past, they just see it as a problem between you and the person which doesn't involve them. Do you think it would be wrong to feel offended by this?

I wouldn't care
I would feel betrayed but won't end the relationship
I would break up with them
