Cheating my boyfriend on pretext of marriage and leaving me later

I am posting this as my boyfriend left me in a disturbed mental state by saying that he is leaving me after making a promise that he is going to marry me by informing our affair to his parents.He even asked me to inform our affair to my parents which I did after which he suddenly changed his mind saying that he cannot continue this affair as his parents will not agree though he told me many a time that its his decision that plays an important role in his family.We had physical relationship and 1-2 times he forced himself on me even when I objected him to do so. I don't know if I can mention the meticulous details but he continued to touch me on my vaginal area with his penis in a hard way ,to be precise all over my private part which caused me pain. I agree that I have been in a physical relationship with him with my consent excluding those 1-2 times which I mentioned above.
