Hi everyone,
I'm getting married to a wonderful man in just under 6 months! It has been a wonderful experience planning it, until this past month. My mother has been super controlling the past month. She wants us to do a receiving line because it would be tacky if we didn't do one (her words), although my fiancé & I plan on going to the guests tables & greeting them during reception. When I told her that we weren't comfortable doing the receiving line, she proceeds to call me names & screams "I don't care what you want." She backed off when we decided that we would cancel our venue if she didn't stop her behavior, but once my future in-laws put money into the venue, she was back on the receiving line. Both times she has threatened to pull funds if we didn't do what she wants. She then started controlling the wedding cake. My fiancé & I were planning on doing a small tiered cake to cut & then serve everyone a slice of cake from a sheet cake. My mom then proceeded to say that that was tacky & that there will be a big cake to serve everyone from (despite us being overbudget & costing more for the big cake). She's starting to control the color of the shoes I wear, wanted my dress to be in a different color (I ultimately got the dress in the color I wanted), wants to cover up the stairs of our venue because it's too rustic for her taste, and wants to turn our wedding into a more formal event. When we've calmly approached her about what we want, she has proceeded to tell us that the wedding isn't about me or us & that if we decide last minute to cancel the receiving line, she will force all the guests into a line while we go get family pictures done & tell them that we are ungrateful for not thanking them in a line for coming out for the wedding. She has lied to me, my fiancé, and his family on multiple occasions about the wedding. She has said that she & my dad have asked me for things, which she hasn't, but has demanded that we do things her way. We are afraid that she is turning the wedding into a super formal event. Despite telling her on multiple occasions that it is our day or what we want, she continues to throw tantrums. We have always taken their (both my parents) ideas & suggestions into consideration so far, particularly the vendors, but we just felt that their ideas weren't us. We don't even enjoy the planning process any more

. I know that whoever pays has a say, but at what point does this cross the line? At what point does this behavior become inappropriate? Has anyone dealt with a similar situation before? Any advice? Thanks!
