<human>: We dated for 8 months, mostly long distance, and I thought it was going really great. He said he wanted to marry me and that he bought me a ring. I was ready to be engaged to him and spend the rest of my life with him. 

Two weeks after he said he wanted to propose, he abruptly changed and dumped me. He keeps lying about the reason. First he said the distance was too hard, then he said it just wan't working out, then he said I wasn't good enough. I tried to stay in contact with him for the month that we've been apart but he's so cold now. I found out that like a week or two after he broke up with me, he replaced me with a new girl and that he's completely over me. 

I'm so extremely hurt that he's acting like I meant nothing. I lost my virginity to him and thought we were going to get married. I want to be over him since I mean nothing to him and he doesn't even want to talk to me, but I'm still in love with him. I can't see myself with anyone else..
