I think I'm in love with my boss and he's getting married next week, is that bad?
Yes probably, what do you like about your boss so much that you would risk ruining his relationship?
He's a very nice guy and a great lover
I understand, but workplaces should always stay professional anyway. You should try to stay out of his love life if he's getting married.
I don't think that's possible, I can't change my feelings.
You are going to have to change the way you feel about your boss, it will not only save your job but his relationship as well.  It's morally wrong what your doing, and you need to stop.
