<human>: My fiance and I have had a hard go. We have been together 18 months thus far. I felt this Christmas was a good time to propose and I did it in front of friends and family. We had been strong for awhile and it felt right. 

The issue is that I've been married before. My gf has not. She wants a glorious wedding with a lot of people invited and tons of expenses. I want a courthouse. We agreed on a half way point. As time and planning has gone on now everyone is invited and we are booking them rooms.  I've kind of gone along with it because I hate making waves but I have hit a wall and life in general plus wedding planning has really frustrated me.  

What I want to know is,  who is out of bounds here?  Can I go back and ask her to slow down,  or even postpone the wedding? 

I forgot to mention I've been in and out of jobs a lot recently due to the soft Canadian economy and money is bad. I'm so far in debt and the wedding will make it far worse. She doesn't seem to care and is just pushing for it. 

Am I a huge dick for wanting to slow down and rethink?  Can I demand a wedding my way so I can buy a house instead of a 1 day party?

Can you summarize the given text in a few sentences?
<bot>: rethinking wedding and relationship in general due to some bad times. Am I a dick for wanting to revisit the entire thing?
