i loved some one to point of extremes , we both are no more together , he insulted me and blamed me without even giving me a chance to explain him ,he believes his astrologer then my words, i need to promise on my beloved god to prove him that i am still a virgin, he always used to say that he does not love me but he is with me for physical pleasure but its just in phones , he never touched me but i feel i have his fingerprints on my soul or should i say we have never being together but i took him as my husband mentally cause in his tensions i used to be his support with my words giving him positive energy, even after a huge accident with worse crushed injured foot i was there for him and so he used to call me as his wife , it has been 67 days that i did not respond to his abusing words in mails due to some misunderstandings, he is very good person,frank but very hot tempered i happened to lie him just once but my intentions are clear i do not have any idea to cheat him, many times he used most horrible words of abusing me like slut and all ,the way he abuses me really broke my heart i truly loved him but he always multiplied my pains with his words, please if any know one know any way to forget some one you really love please tell me ,i could not sleep , eat or study i am a medical student i cannot take this any more i love my parents for them i really want to forget this person cause its hurting me and my family , i am getting suicidal tendencies but i am not a coward to quit life and punish my family ,i even went to psychiatrist but it did not help me much ,it really hurts if any one who had went through this phase and found better way please please suggest me cause i am tired of smiling artificially for my family by keeping pain inside, may be i can never accept any men that's for sure for rest of my life but i need peace at least to survive , i am posting cause i need not reveal about my identity ,i do not want any one of my friends and family members know that i still did not forget him cause for them i am happy and busy and that is what i wanted so that they can continue there routine with peace may be stranger can suggest me better way without giving me sympathy
