The man of the house is hitting on me

I am a house girl in one of the posh estates in Mombasa.  I know I am pretty because men tell me so. I have a very good employer who treats me well.  She is married and has two children. I have been with this family for three years. The problem is that my employer’s husband has been hitting on me for a year. Though he is persistent, I have never given in to his demands. He always sneaks back to the house to come and disturb me. Should I tell mama about this?
