I dont want to get married
It's not so much the idea of committing to 1 person
It's more about the extravagant amount of money wasted.
My GF says shes wants a wedding of ~100 people
Some preliminary planning shows her unwillingness to cut cost here or there, she wants to full package and the fact that she doesn't have the money to pay for it dosnt seem to factor into her thinking.
She says things like "your supposed to spend 3 months salary on a wedding ring"
I feel i should run away, should i GTFO of there?
You should take full control and cut those expenses to moderate rate. If she can boss around you in this then your marriage won't last.
