When we are in love, we sometimes do the oddest of things, like stop thinking of ourselves completely and put the other person on a pedestal. Cut of ties with everyone else, as we feel we have found the anchor to our life. This is a beautiful safe feeling, unfortunately only till the bubble bursts.
Even though it may be very painful right now for you, try to look beyond the hurt, the rejection, the bruised ego. This would be a good time to do some introspection, for self realisation, for clarity. Whatever you feel is broken outside, has to be fixed from inside first.
We must accept ourselves as we are. It is only when we love ourselves for all the good, and the not so good qualities that we possess, that we start enjoying our relationship with ourselves first, and then with others. We must first identify, then accept the not so great areas of our life, and find solutions to work on the areas that needs change, to bring about the desired results. And see how life changes for the better when we empower ourselves. We must first of all stop judging ourselves so harshly. When we judge our emotions, it prevents us from understanding them. So when we accept that we do have limitations and are willing to work on it, then we really start loving ourselves, for all that we are. When we start loving ourselves for who we are, then we will automatically attract positive people into our life. When we are not operating from a place of insecurity, we will then attract secure relationships in our life.
Hope things will work out for the best for you.
