I think I want to start splitting the cost of my dates.
Why do you want to split the costs?
My ex-girlfriend used to be very generous with money and drove me everywhere. I got used to it.
You were spoiled by her, but it's good you aren't trying to put it all on the new girlfriend. One person should never be expected to pay for everything in a relationship.
Trust me, I would rather keep the costs low because I'm trying to keep this new relationship balanced.
It's a good thing you're not placing unrealistic expectations on your new relationship.
