one sided friendship happens when only one party knows about the friendship but the other is oblivious. while no friendship simply doesn't exist.
One-sided is when one person is giving all the emotional oxygen to the relationship. Unless you are pretty centered, that scenario will wear you down and take chunks out of your self-esteem.<br />
In my opinion, it's better to be alone than to be caught in that kind of trap. <br />
In one-sided friendship, one gives more than the other. In nil-sided friendships, neither party gives.
there isnt one.
