So ive been talking to this guy from school hes a senior and im a junior, we basically have the benefits that cupples do.. but we arent dating. The point is that prom is tomorrow and i cant go with him so hes gojng with friends, i told him that hes probably gonna dance with girls and he said "maybe..its prom lol" and im not comfortable with the idea of him dancing with any other girls. What would you guys do?
