It's sounds to me like you did the right thing. I dated a middle eastern guy for like.....2 weeks. I wasn't all that attracted to him either. Just not my type. But you defiantley did the right thing by telling him how you felt. I went out with a guy I met on the internet, it was horrible but he thought it was great. I felt terrible, but instead of confronting him I jsut stopped answering his emails. I still feel bad about it.
Keep looking...you will find somebody right!
