Am I a bad person?

Every time my boyfriend makes jokes by commenting on other girls saying how cute they are and has the nerve to ask if I let him have his friend girl as his other girlfriend (the one who he had said that have a crush on him but who seems to have finished talking because they always fought because she always fought the one who broke up with me and he gets angry with her for that ending in one of his many discussions) I usually think to myself that my boyfriend would never have a girlfriend if it weren't for me and that if someone falls in love with him they will end up wasting time with him because of his childish and sometimes idiotic personality, Does that make me a bad person?
