i love a man had we have been together 4 more than 2 years and we know each other very well. Then a man came into my life as a friend and he used to advise me to stop caring about my love, and by doing this he always use to do brain storming and i did not understand what he wanted. and finally he had sex with me. i do not want to do that and then i stop talking with that man.

he then called my lover and so i have to tell every thing to my lover that that man had sex with me. what should i do? my lover has left me, he do not love me any more.

i have apologized for so many times but he did not accept this. i want my lover back. please help me. please i really love him so much and he loved me too. he has started taking drugs.
