Annoyance over sister's wedding...

Firstly, my husband I married around 4 years ago and my sister was my maid of honour. She had everything paid for by us (outfit, hair and makeup, flowers and accommodation) so she didn't occur a single cost. She caused a lot of drama and I had to change several plans to keep her happy.

She's getting married and I'm not in the wedding ceremony so have to organise my own hair and makeup and outfit etc. she agreed to pay for a room but has now complained to my parents that she doesn't want to/isn't.

I'll have a 1 month old and 4 year old at the time of wedding and it's a good few hours drive.

I don't want to cause issues but at this point don't think the hastle is worth it especially after all of the expenses we'll have. We're not close and might text or clall every 3-6 months and we see each other one a year at the most.
