Do I have to invite her to my wedding?

I recently became engaged and I have yet to be congratulated or anything by my aunt (my mom’s sister). She knows about the engagement but she refuses to say anything to me because apparently she doesn’t like my fiance (for no good reason). I am really hurt that I haven’t heard anything from her. She has told my mom however that she expects to be invited to the wedding. I don’t want her there considering she does not like my husband to be. She is a very childish and rude person but she is important to my mom. I’m not sure what I should do in this situation.
