Non-virgins need to split the bill. You already gave another man what was supposed to be special, so do not show up expecting full treatment for leftovers.
 
Divorcees need to pay the whole bill. You had your chance, you blew it, and now you want another man to clean up what you could not hold together. No. You pay.
 
Single moms do not just pay for the entire date, they owe compensation. That man is not just dealing with you, he is stepping into a job someone else walked out on. So yes, you cover dinner, and while you are at it, hand over a Rolex for each kid he is expected to love like his own. You want him to act like a provider, start by paying like one.
