that's true this guy is not interested, just let him go ! There r 2 possibilities in my opinion. He can get interested if u show him that u don't ever mind or he simply isn't the right guy for u and u'll soon find much better.
HI I don't think it's urs coz u said that the last time u saw her was the 4th day after her period. Now it's better for u to be carefull with all that ! U need to talk sewiously about ur relation !!!
