mixed race gal all i can say is that if you don't trust the brother, then you heart is probably telling you to drop him and move on,if you are just being alittle paraniod, give him the benefit of doubt and see if he'll change his ways.remember you don't have to wait a lifetime 4him to change coz change can take place in 24 hours.however do concentrate on ua studies and don't loose any sleep over a GUY.
