I’m a Graduate & My Boyfriend Is a Driver, I don’t Love Him anymore – How do I Dump Him?

Dear Readers, I am a 27year old female. My parents died when i was 8 then I dropped out of school because no one could afford to pay my fees. I then met this guy when i was 16 and he sent me back to school. He was selling fruit then but still he was Able to pay my fees. He then got a job as a truck driver and sent me to University. My problem is that i feel i can’t continue with this relationship because he is not my type and i don’t love him anymore, he isn’t fluent in English, plus some other Personal stuffs. I feel I have paid him back for his Good Deeds because I give him s*x anytime and anywhere he wants. But now he can’t meet up to my demands. How best can i tell him that he is not my type without hurting his feelings?? I am grateful that he sent me to school but i can’t be in a relationship with him anymore. I want somebody in my own class not a truck driver. Please help!
