I was invited to my partner's daughter's University event. His 2 other adult children also came. I bought coffees and snacks and bought drinks in the pub. I bought his daughter a pretty vintage top she had seen as a surprise. Out of nowhere my partner accused me of being tight, that I should have bought some of their meals as means of showing gratitude for having been given a 2 night break. I paid for my own meals or transferred money to my partner. He called this pathetic. I was going to contribute fuel and campsite costs. He said that I am tight fisted. Just for the record, I have always given generously to him and his children and what hurt is that he said that he is a generous person. This is not the case. He doesn't buy gifts and has never paid for me and my children, who weren't even invited to the event. What are your thoughts?
