What does it mean when you dream you're going out with your boyfriends cousin?

It may just be that you have been cheated on before, or you feel so attached to this guy your afraid that your going to loose him, you may not feel good enough for him and feel that he is so great that everyone would want him. It dose not mean that he is cheating. Signs of cheating are making up excuses to come home, getting caught in lies allot and may uninterested in you or overly interested. I say don't worry, if you haven't seen it for yourself, (other than in a dream!) But you may want to consider what you would do if this circumstance were to happen in reality, how would you respond; would you cry and just except it or would you cut him loose and be strong and not let it effect you causing depression. Maybe you just need a little more attention. Or giving him more attention, not overly but enough to let him know that you are proud hes your man!
