I'm planning a wedding, and I'm on a lot of bride groups on facebook and read a lot of wedding-related things online, and I've noticed a massive trend that in people having mothers (their own or their partner's) turn into complete narcissists during wedding planning. We've had a few issues with our own being demanding, but I mostly wanted to know if anyone here has BEEN a Mother of the Bride/Groom who has been demanding about your child's wedding?
E.g - my Mum completely put her foot down when we discussed getting married just the two of us. She said it would break her heart etc., and she'd never get over it and would write me out of her will!!! We've had a couple of similar amateur dramatics from both Mum's over very minor things, so it's not just big stuff. That's a common theme in the groups. I'm fascinated by this complete 180 some people (and it is almost always Mum's) seem to do when their children get engaged. In my opinion, if you're not contributing a significant amount of money to the wedding, you don't get an opinion. If you're asked - sure! But even then the couple don't have to take your advice.
So - why? Have you ever behaved like this about a wedding? What was the thought process? (Or what do you think if it happened to you!)
