One of the things that happens in a relationship is that one or both of the partners feel themselves attached to each other, they feel like they're one with each other, right?
You need to learn to detach your feelings and connections to this person and start a deep connection with yourself, I know it's hard in the beginning, but you have to try it.
Start doing things for yourself and live your life for yourself and those around you which will make you feel better.
