Dear Annie: Is it fair we split every bill 50/50 but boyfriend makes way more than I do?

Dear Annie: My boyfriend loves going out — bars on Fridays, a nice dinner on Saturdays and at least one weekend trip every month or two. We’ve always split the bill right down the middle, no matter what we order or where we go. The trouble is, he makes quite a bit more than I do, and he’s just a bigger spender by nature.
