One of my cousins is getting married and is going through the wedding preparation process at the same time I am.  My mother has to hear about all of this on Facebook & from her brother (my cousin's stepfather).  So now my mother is getting pushy with me to "outdo" my cousin.  Honestly?  My cousin (who is generally pretty spoiled) probably has a bigger budget than what I have, but I don't care. It's her wedding, not mine, and I'm trying not to let it affect my planning.  But my mom's turning into a royal nag about it.  How do I deal with this?
