Many nights out with friend. Quite a lot of these I felt were me paying more - on many occasions I paid for all the cabs on our night out. Some nights she would comment what a cheap night it was. It may have been for her, but I paid £30 more than night and were were together all eve and drank the same/ at the same pace. I don't know if she was purposely doing this or was drunk and didn't have a clue.
With that in mind, lately when she pays for something small ie under £10 and says (out of politeness and awkwardness only) don't worry about paying me, I won't pay her as she owes me.
AIBU ?
