In laws wedding planning stress.

So my fiancé and I decided to pay for our entire wedding ourselves mainly so that we could make all of our own decisions and really have our wedding our way. His parents were not happy with our 85 guests and the fact our wedding was on a weekday. After many discussions and meetings we agreed to invite the extra guests and they would pay the difference.


So. We found a venue we love and it recently had a cancellation and had Saturday available. (Perfect for them right) only thing is we have to book ASAP because 2 other couples are interested in that date since it is the only weekend wedding available in September.
Well now since they are paying for part of it they are making us get the okay from them and won’t give us the okay... so basically they want to control where we get married now too (the entire reason I didn’t want anyone helping us pay) I really have no idea what to do if we book this date with our their okay we won’t be able to afford the Saturday wedding in the long run and will have to put it on credit . If we don’t book we will lose the date.
I feel like they are hanging money over our heads when we didn’t want their money in the first place they offered it to us so that the rest of the guests they wanted to be there could be there. I’m so frustrated and losing excitement for my wedding
