Dear One,
I wish you were here so I could give you a big old hug and some fatherly advise. Can not get my arms around you from here, but I can offer you some counseling.
First, be assured that this too, will pass. Second, you are young and to be honest probably don't have a clue as to who you really are. Not knowing who we are, we misplace a great deal of personal-identity upon the person we are most intimate with; and this is often too heavy a load to bear for our beloved. The relationship is doomed.
I suggest you take this new opportunity of freedom to spend more time alone discovering your inner most senses of life and existence (spending time in nature and meditation is conducive to this). Open and come to genuinely know your being and your relationship with Life and universe, and then, and only then, will you have true integrity and love to offer others. For as long as we do not really know our inner authenticity, we live a lie, and all we have to offer others is counterfeit.
Peace be with you, friend.
