i dont know

i was with mt ex for only 2 weeks when he broke up with me, he said he didnt want a relationship yet and that he would call me when he was ready, but 1 week later he had another girlfriend that he claims to be in love with, he knew i cried when we broke up, but every time i saw him or one of his friends i would start acting as if everything was 100% better, when he saw me i turned around talking to my friend laughing like crazy but he still wont talk to me and its been over a month...the act like i didnt matter thing so didnt work..
