when can you say enough is enough???

i am sad to know it..sometimes we just don't noticed that we become stupid (so stupid) especially in a relationship which you really wanted to work with the person that you loved.. and because you wanted to protect and prolong that relationship sometimes we don't notice that we already forget ourselves and we become someone else , someone which is realy not us.. but there would really come a time that you will realize whats going on especially to yourself and maybe this will be the moment which you can say enough is enough.. thanks for the responce.. good luck to you and to your daughter!! don't lose hope! God bless!!
