Hello! My family has generously offered to contribute to our wedding. My Dad and Step-Mom, my Mom and Step-Dad, and my Aunt have all offered to contribute. Both sets of parents have sent the amount they said they would give. My Aunt is rather flighty, so I asked her if she was still able to contribute a few months ago. She said she was and sent us a check for half of the amount she had offered and said she would send the rest later.
Fast-forward to now (less than 6 months to go!) and I have several large payment coming up in the next 2 months that we need her remaining 50% for. After she sent her first check she has mostly disappeared from my life (work, new relationship, etc.). I have attempted to hang out with her several times, invite her to wedding appointments (she always cancels last minute) but she never follows through. I can cover the remaining amount that she offered myself, but it would put a damper on our current lifestyle (i.e. we won't starve, but won't be able to live how we currently do) and honeymoon plans.
I'm incredibly awkward when asking for things (more so when $ is involved), so I'm looking for the proper way to approach her about this - or should I let it drop?
Thanks.
