Why is it hard to meet genuine people?

I am a very social person. I enjoy helping others without sticking my nose too far in and people come to me for advice and understanding.They call me often to talk and for help. I am also very honest, but never in a nasty way. I express what needs to be said in a way others can understand without sticking the knife in further. I love helping animals and others with life problems and have taken up Psychology. I am also very honest with myself and I know I can be so honest people seem to be afraid to be honest with me. I think they feel if they have been dishonest in the start, that I will flip, which is not the case, I always explain it’s the lies that I havent got time for. I find it hard to meet genuine people, they say they will call, or go for a drink but never do. They ask my brother who is outwardly selfish (but i love him) and does not consider anyones feelings but his own. Hes committed fraud, lies to me, spends every single night at a couples house he knows and never considers they might want time alone. Yet he gets invited over all the time. I never done anything wrong to them. A friend once said, “leave silly people like that alone, they dont deserve your genuine friendship” but why is it genuine people are few and far between? Im so social and love life, yet im always left behind.
