What guy buys shoes for another girl unless he is sleeping with her or wants too. I'm not stupid what does he think I'm stupid; he's stupid. I have brothers; i feel taking your date to buy shoes for another girl is weird. I am delayed reaction and learning to communicate so I can't communicate my feelings which are hurt & upset. I don't care that he wasn't buying me shoes it was the fact he was buying some other girl shoes; way to make a lady feel special. Then he asks me what shoe size I am; I say eight or eight and a half. He asks me would I want the shoe to fit bigger or tighter. I told him I like a shoe that fits. He got upset and said I was too difficult to buy shoes for. Red Flag. When is wanting your shoes to fit equal difficult. We had fun before but this date was a total bust. I just wanted to leave. He wants me to go up to his place. I go up to his place only to hear him call her that he got a surprise for her and to come by. Guy who buys shoes for for another girl while on a date. Red Flag.
