Being used as a beard?

I dated this guy and he was horrible to me. Always put me down, made me feel undesirable, criticised my looks and my every move. He never wanted to have sex, and always blamed it on me. He completely destroyed my self esteem. He even broke up with me by just ghosting me and never hearing from him again. I found out after we broke up that he came out as gay (not bi). It made me so angry that he didn't just use me to hide his sexuality, but he also treated me like shit because he wasn't attracted to me since I'm not a man. Why would anyone do that? I know that coming out is difficult, but why use someone, and not just stay single? How would you feel if this happened to you?

PS: A beard is a person from the opposite sex that a gay person dates to hide their sexual orientation.
