i'm sorry to say this but i'm not a fan of people expecting and almost obliging others to help them. if others help you, then you're blessed and lucky to receive such help. but you should not be obliging others to help.
this is just the start. when you start having babies and all, you should be more realistic and more fair when expecting help (you shouldn't).
Print out this website page and hand it to each of them.
It contains a list of the duties of bridesmaids. Say to each one of them, "I didn't know if you knew what you were supposed to do, as my bridesmaid, so I printed out this sheet for you. I know it's a little more complicated than you probably realized, but I thought you might want to read about it."
They're not friends and probably just jealous.
I'm sorry to hear that. What do you think is going on? Have you asked them about it?
If they're constantly putting off spending time with you in preparation of your important day, it might be time to re-evaluate if you want them to play this role. It may be more hassle than it's worth? Have you considered downsizing, just to make things easier on yourself? What if you stuck with one really good friend instead?
