For example: I asked a friend to go somewhere with me. She also invited another friend to go with us (I told her she could invite anybody she though would want to come). The tickets were cheaper to buy together so I put y'all 3 online ($90 each)

When I told her I had them she asked how much they owed me. I hesitated but told her.

I feel weird in situations like this and in the past have said "no, it's ok, I got it" even when I couldn't afford to have gotten it. Like I invited someone to go do something that was kinda expensive and feel like I have to pay, if that makes sense.
