So a while back I bought for my female friend a birthday cake for her birthday that I paid about almost 70 dollars for it. I was more than happy to do that for her only for her to get engaged shortly thereafter to someone else. I was friend zoned but I still stuck around hoping that one day she would realize that I'm the one for her and that I truly cared about her more than anyone else. She kept her whole dating life a secret from me and everyone else only for her to drop the boamb shell news shortly after seeing her. I was devastated cause I didn't know. It would be a different story if I knew beforehand and knew that she was off limits and would have time to prepare my mental state but I didn't get a heads up or anything and she rather hid it from me and everyone else around her except her family. Her co worker though everytime seeing me always asks me if I have a girlfriend or a wife yet and I simply replied not yet and I even told him that if he or she knew anyone to set me up with them. I don't know what's wrong with me but I'm just severely piassed and I thought about footing her the seventy dollar bill for the cake but I'm having some doubts about doing it. Would I be an asshole if I were to foot her the bill for the cake ?
