Please please please answer, not to long. thankyou so much! 10points for best.?

erm so me and my ex who ive known for ages and went out with then we stopped going out over a long story... anyway we are now friends but im kinda worried because if we went back out and it got serious i dont think he would get along with my family when i introduced him to them, because i have 2 brothers and there into football and different music than he is and my ex hangs about with girls mostly becuase he feels as if he has more in common with girls becuase he doesnt watch football etc.. hes not gay tho defo not, erm what can i do about this problem? also my bff told him i was fostered so its kind of awkward all the time now and he always jokes about, calling me a paki cuz i wear fake tan but he is only joking tho i actually am a half cast but i havent told him yet, i look purely white and a lot of ppl dont believe me when i tell them im half cast i just took after my mums colour i think, but my brothers are tanner than me, so im going to feel awkward if ever introduce him to my family, becuase il be white and then be dark and he wont be able to talk with them about football or nothing becuase he doesnt like it so it'll be all ****** :( how can i solve this? becuase i really like him and i dont want this to ruin it if it did get serious...
