Well mate I went through this many years ago as I’m am sure 1000`s of others have. It is very common.
I cried for weeks I had never had a broken heart before; it was incredibly painful, I saw her in every woman who smiled at I Passed or me. She was from Hungary and so when I would hear an eastern European accent it would drive me crazy.
I tried to forget her, Impossible. It reminded me of my dad I always wanted his love but could never have it the way I wanted it.
Truth be told I was an unhealed person in the area of healthy relationships and so I was truly not capable of having one, a balanced one that is.
No matter what you do or how hard you try, you cannot make someone love you.
Either they do or they do not.
God used this unhealthy relationship to draw me closer to him; after all, he was the only person who could give me peace and comfort during this time.
It took about three to 5 months cannot remember exactly, but when I was finally able to accept her as a friend in my heart I was Avery healthy man in that area.
I truly believe God engineered that situation to draw my attention to him so that he could heal me in that much needed area of my Heart.
I was 21 at the time, long time ago had forgotten all about it until I read your question.
My heart truly goes out to you, but take it from me you will get over it if you allow God in to your heart to take her place and because he loves you so much he will heal you with his wonderful loving touch and send you his best pick of the fish in the sea if you will Dare to trust Him!!
I honestly believe Jesus is the only way, after all God sent Him to die for us to Heal a broken relationship :0)
You are in my prayers friend.
