Did I overreact and break up over something stupid?

for a while now I've had this break-up in my head and it just doesn't make sense to me in the least. essentially me and her dated for 3 almost 4 months. during the argument that led to me ending it with her she said "i never really liked anything about you I just liked the way you made me feel". But my main whole issue was that the whole time we were together the only times she actually seemed happy with me was when I was spending massive amounts of money on her. the second I told her this she had a look of complete shock on her face and kinda looked like her brain completely shut down because all she did from then on out was repeat "my friends were right about me" yet the only people she had ever introduced me to was her mom, her moms b/f, her adopted brother and his g/f. none of which were the friends in question and she kept acting like I knew those very same friends that said whatever she was saying they were right about at the time and never answered the question of what her friends said. I mean I was dropped a hint about spoiling her by her own moms boyfriend but didn't put 2 and 2 together and was wondering if I helped feed the break up in that way by somewhat spoiling her and turning myself into a tool. its only bothering me now for a few ideas got put into my head by people around me and now I can't stop thinking about the what if's
