I am Mexican, and my FI is American. Though we aren't engaged by American terms - meaning he hasn't proposed - he has already brought his parents over to my parents house and asked for my dad's blessing to marry me, which to MY family means we are engaged and planning! (We already have a date set, just waiting on the ring!)

Anyway, my mom is VERY excited - I am her only daughter and, with my FI's agreement, we are planning a traditional Catholic wedding and a traditional Mexican reception (dollar dance, baile de la vibora, mariachi, etc).
So of course, in keeping with Mexican tradition, my mom keeps telling me that it's the mother of the bride and family who plans the bridal shower, bachelorette party, look for the bride's dress... basically, she wants to be a part of everything! Which is pretty much fine by me and my FI, and I think she will be fine to let us pick out things on our own when we want to.... but the problem is she is already getting defensive because I told her my MOH and bridesmaids (in American tradition) will plan a bridal party only bachelorette party and usually help the bride get ready on the day of, etc. She got a little dramatic, "I guess I won't get to help you do anything", and of course it is stressing me out!
My question is, what do you guys think I should do in splitting up 'jobs?' My bridesmaids are already talking about planning things as well as my mom. So I was thinking my bridesmaids will help me pick out their dresses, plan my 'bridesmaids only' bachelorette party, where as my mom can throw a bridal shower (which in her eyes will be the despidida de soltera) and give her input with the little details (flowers, invitations, etc)... thanks!! Sorry so long!
