AM I COOKED 😭

So for the first time I met someone that is into me and I think she's really nice and pretty so we have been in touch and talking for the past week and have been slowly progressing and getting to know each other. Today I learnt that it is a 1.5 year age gap. Idk how to feel about this. She's born the same year as my younger brother which just feels wrong. Idk what to do.
