My girl friend cannot do any house chore

Dear Counsellor,
I am a 25-year-old graduate working in Kigali, Rwanda. My first girlfriend was Rwandan. She cheated on me many times, yet we had promised to abstain from intimacy until she graduated. She cheated on me with educated and illiterate men alike. I was so traumatised that I swore never to get into a romantic relationship with any other educated woman.

Two years after this ordeal, I fell in love with an uneducated 23-year-old Rwandan single mother. In December 2011, I introduced her to my parents and I enrolled her for vocational training. She still lives with her parents, while I am renting an apartment.

However, my girlfriend is so lazy and whenever she comes to visit me; she does not lift a finger to help with housework. I do all the house chores alone. I must cook, mop, and wash the clothes and dishes, among others, while she watches TV. Disturbingly; she has never laid our bed even when she was the last one in it. My workmates have advised me to leave her.

What should I do? Should I retract my decision against educated women and marry one?
