I Know What Unrequited Love Feels Like

Feeling broken,empty and lost. Not knowing where to go or what to do. I had a realization tonight. Love hurts so badly! I really thought we would be together in the long run. But he choose her. I lost my 4 year battle. Yeah you read it right 4 years of my life on who I thought was my soulmate just to have my heart rip from my chest. I don’t understand why these things happen just that it make it so hard to trust and let others in. Please tell me there a happy ending.
