1. The dinners
Most guys would define dinner dates, as 'polite enjoyment', where you know you are supposed to be enjoying, but are not.
The plus point is that, for women, it is never about the money spent. They just expect to dine in a somewhat dignified restaurant. The problem arises because your concept of 'dignified' differs vastly from hers.
Invest time on sharpening your culinary skills. Start cooking meals for her.
Yes, it is a big step, but you can't cross a chasm in two small jumps.
A reasonable meal will earn you big brownie points and keep your notes snug in your wallet.
If there is no escaping that, avoid drinks and desserts at fancy restaurants. They are generally responsible for half your bill.
