my Partner cheating means im ugly

I was cheated on by my boyfriend! I couldnt believe it!I feel now it was my fault! I guess i should'nt its not like I made him! he would always leave to go to his friends and lie about where and what he did and not tell me the truth he also kept it in for a year!I feel very ashamed in my self and ugly. I saw the girl he cheated on me with and she was ugly in my eyes and that made it worse. The worse part of all was finding out why he cheated, he did for money!!!!
