Or you can just accept that some people is not going to like you and move on until you find someone that does like you. I mean, lets say that you like to joke about rape, well maybe someone who has been raped is not going to be a good partner for you. Or a feminist. Hiding it that you find rape funny or arousing might trick her for a while, but eventually she would find out and break up. Just accept incompatibility and keep looking.
