why is relationships so hard ?

Well thats because we all feel that we need to dominate the other person in the relationship and we seem to have lost that patience and passion that we need to have in a relationship. other than that, we all expect only the positive things and we don't want anything negative. But, we forget that the fact the, like the two sides of the coin, relationships will have both the positive and negative effects on it! Its just that, we should tolerate things and understand each other. If there is understanding and tolerance then relationships are easy as you said! Cheers! Happy Mylotting! :)
