Exec board kind of corrupt?

[Jp685]

I'm the social chair for my sorority, so I'm in charge of planning formal. We haven't had socials for over a year and we only have formal once a year. They gave me $1500 as a budget for formal and I figured if I charged $35 for tickets it would cover a really nice formal (usually our formals are crappy). I was told however I wasn't allowed to raise tickets from $30, and now we can't have a sit down dinner only "snacks" like cheese and crackers. I was a little upset because what kind of formal is that? I'm also a senior so I want my last formal to be memorable and not another formal with a bad DJ and bad food. So that's my problem with formal is that they won't let me raise prices or give me more money to make the formal nice.
I recently learned however that the entire Exec board of 6 girls had a retreat in another state using our money from dues that was not authorized by the rest of the chapter. They also admitted they bought monogrammed sweatshirts for themselves only. An advisor from National came down and told them they had to buy something for the chapter to "make up" for the money they used from OUR budget. So they bought us all hair bows with our letters printed on it. Which in my opinion isn't equivalent to a beach retreat or monogrammed sweatshirts.

None of my other sisters like confrontation and most of them aren't even aware their dues money was misused. Some of them have asked to see the budget, but the finance chair still has not honored their request. I am standing up in front of the entire chapter next week and confronting Exec board myself for an explanation. I sent them an email telling them my concerns and they got really defensive and gave me attitude. I've never had a problem with any of my sisters and I've always been very reasonable. However the way Exec board treated me when I was looking for answers was incredibly uncalled for and unprofessional. It's so bad that if the meeting next week does not go as planned and they do not give us an explanation or change their spending I'm considering disaffiliation. All I ask is that they share the budget with the members of the chapter and we vote on how the money is used. Am I wrong for thinking that the budget shouldn't be used for a select few of the board members without the knowledge of the rest of the chapter? Because the members of the board seem to think that they have done nothing wrong, and that really bothers me. I am on the exec board of an honor society and we always get input from the rest of the group before we make any decisions. I think that's how it should be. I really feel uncomfortable being in a chapter where things are happening behind closed doors without my knowledge and with MY money.

But anyway the Exec board is really unhappy with me and plans on giving me my disaffiliation papers at the meeting. I doubt my sisters will stand behind me because they're too afraid to confront the group, even though they have told me they don't like the Exec board at all. I just want your opinion about whether or not I'm overreacting. I've been in the chapter for over a year and have made such close friends, and disaffiliation would be sad for me, but I can't stay in the group if this is how they are going to continue to operate, especially if the advisor from Nationals condones it. I really appreciate your input.

Edit: I also found out that exec board is talking behind my back to other sisters saying I'm out of line for the email I wrote which just had a list of my concerns about the budget and the treatment of the chapter (Eboard is rude to the chapter and yells at the new members, and gets defensive when someone offers suggestions about how to be a better exec board). They also brought my boyfriend into it who is in a fraternity stating that he is the reason I sent the email and he's a bad influence on me. Because I've never had a problem with Exec board before, I've never told them any concerns, but now that I have concerns I am confronting them about it not sitting back and watching. The fact that they would think my boyfriend who is completely unrelated to the topic has anything to do with my actions really offends me and makes me wonder if my sisters even know me at all.
