There are various level of friendship and they do not all have to same levels of commitment or caring at all. If you meet someone and you have an instant connection with that person you may feel that it is because they are meant to be your friend forever. This is not always the case. Sometimes that energy you initially feel is the pull of the negative and positive energy of two people. This could be a good thing and in the end it could actually turn out that that was a sign of two energies fighting to find their strength and power source. A negative can drain a positive and a positve can power a negative. We just never truly know until we give the friendship the time it needs to work through all the highs and lows. A positive energy is naturally drawn to the negatives. It is their mission to give power to those in need but they can over do it at times and find themselves in a very dark negative relationship and then not know how to get away and regain their positive energy. Negativity is like a Cancer and can spread throughout us and then to those near us if not addressed.
Always take the proper amount of time to evaluate every friendship you have. There is nothing wrong with taking a stand for yourself and implementing firm boundaries. These boundaries are necessary at times to keep you grounded and of clear mind in order to make sure that you have the right people in your life. Our true friends will understand and have boundaries of their own.
