caste problem between me and my partner

Hi, I am anandhi 23 yrs old BA.LLB final year student and i had love affair with same class mate name madhu 25 yrs old, we both loving for 4 years and still continuing but now few months he started avoiding me and no love and affection from his side i was worried y? and i asked him y ur not like before i am feeling uncomfortable with u?. Then he said in his family they will not allow to marry lower caste girl my heart broken, thing is he already knew that i am lower caste girl.! Basically i am from poor family i love to study but no money, i supported by sponsor i am studying, he proposed me for 1 year, later on i accepted bcoz of his torture. Now i can't imagine marriage in my life bcoz i cannot be free to a guy whom i marry already i had sex with my boyfriend i am feeling guilty and feeling what to do?... Is there any solution for my life please.
