I just got engaged last month and want to get started on wedding planning asap. I want to at least secure my venue and ask my bridal party to be a part of the wedding. We are on a tight budget of 10k or less. My mother has offered to pay for my dress and well as the bar (only if diy bar venue). My father will also contribute to the wedding. My fiance's mother is an event planner and before we were engaged stated she would help plan the wedding (she can secure deals on chairs, tables, flowers, decor) , now she is backing out because I am not agreeing with her expensive ideas. She is suggesting I rent super expensive venues (20k for the venue without food or drinks included).
I let her know we were trying to have an intimate wedding (no more than 100 people) and she kind of threw a fit about it being her only child who will be married and now its going to be a tacky wedding. Mind you she hasn't offered to pay for anything and has commented that the wedding is the responsibility of the brides family.
Has anyone had to deal with mother in laws causing drama before the wedding? How should I go about dealing with her?
