It depends on what this bad habit is and whether it will affect our relationship. Avoid this aspect and get along well. If it is an unbearable bad habit, I don't think I can continue to be good friends. Since we are friends, it is good to get along normally. If it is a habit, it doesn't matter. You suddenly find that you can't stand his own habits, but if he is nice, you can continue to associate. But if you find unbearable bad habits in your usual communication, this is my first point. If you can't be good friends, just get along as normal friends.
