Is it possible to fully restore trust in a man that has cheated on you?

I have been datin this Kenyan guy for about 8 months now. 3 months into the relationship he took a trip back to kenya and ended up cheating on me. I found out through facebook, the girl contacted me and her picture was the 2 of them in bed. I love this man and he has treated me very well. he does not see this as a big deal but ever since then I have had a very hard time trusting him, and find myself getting very jealous when he talks to any female. It dosnt help that he speaks swahili, and I dont know what he is saying... I dont know what to do!!!!!
