A WOMAN HAS DESTROYED MY DREAMS

I am writing this anonymously because my story is a difficult one and am a well known Kenyan in UK. I brought my girlfriend to be with me from Kenya. I had left her there for two years. She had came to join me and i struggled to educate her in Universit and we kept supporting her "sisters child" back in Kenya. She got pregnant while in 3rd year uni so i had to work night and baby sit during the day for her to go uni. Anyway after graduating and getting a job, she confessed that she had a child in Kenya and that even the one i have been bringing up is not mine. She simply saw the opportunity of a good life and she took it. She did not love me and she had to put with all my love which was suffocating her. I was destroyed phyisically, mentally financially, name it. i had become a loser, a laughing stock.  How will i ever get over this mess? Why do women do this things...
