Why did he lie and tell me his girlfriend was his sister after asking him?

Without knowing anything about him, you, or the relationship between you to (or lack thereof), my first assumption would be to make himself appear single either to avoid making you lose interest or to leave open a window to pursue a second relationship or prevent you from becoming upset. The reason can vary greatly depending on your circumstances.

Lol, wow great choice in men you have. I guess he thought he could slip that one by you. He lied because he got caught, DUH. Is that all that matters to you, WHY he did it? Just mind boggling how women think.

Obviously, so you wouldn’t know she was his girlfriend. You don’t tell a potential fuck option that you are taken
