Wedding doubts

So Aaron has been really confusing me..

He keeps talking about how much the wedding is costing etc, and how broke we're going to be.

So I tell him that we need to stop and think about it before we put down anymore deposits.

We can just get out now before we give up anymore money. I've said that we can cut down on costs by not having food. We can just do some appetizers and have an evening wedding like instead of 5 have it at 7:30 or 8pm.., where the focus will just be the wedding and a dance with cocktails after. If we cut out the food it will take away about $3000. Thats a lot of money. We could definetly tell people that its a cocktail reception.
Or.. we can get married and just have a cake and cocktail reception at the place we're getting married..
Or.. we can just ditch all the deposits and run off to Hawaii and get married... cutting only about half the costs, but at least giving us a honeymoon.

I just think that.. why in the world are we having a wedding when no one really seems that excited about it except for me and Aaron. Aaron's family told us that they wouldnt care if we eloped (and we hadn't even brought it up or anything, which makes me think they sit there and wonder about how much money we are spending and why.. when we can just run away and get married...)
My family .. or at least my mom .. isn't coming because she can't behave herself and doesn't really care if she comes if her friends don't come. My grandma - who fights with my mom all the time - is threatening not to come if my mom doesn't come.
My bridesmaids are all battling over what the dresses will look like, the color..anything. Maya wants a black dress, Donna wants big straps and a long dress.. Jenn wants a brown dress (but she really doesn't care either way)...
All the vendors try to screw people over, but I think we finally found some people that are more affordable.

Nothing we do, seems to please anyone. Everyone seems to find issue with anything we do.

The cake, and the caterer are pretty much in the bag.. leaving the dress.

Oh the dreaded dress.. I was already having a hard time finding a dress, because of size issues, when my sister (who is buying my dress) cut my budget pretty much in half), now Aaron said he'd supplement whatever my sister pays for with what the dress I love costs - within reason. I'm thinking an extra $200-300. Its hard to even get people to go with me to look at dresses. Plus I've already pretty much lost a friend, my family doesn't seem to care and I have to wonder why we are doing this elaborate wedding when no one even cares if we get married here or not.
