How do i break up with him?

I have a boyfriend that i have been going out with for 6 months. I have come to realize that i dont love him anymore. i don't know if i ever had really. but i dont know how to break up with him and i am too scared to. He has older friends that really scare me, he is (sorry to say) overly obsessed with me. He is in the middle of final exams and im a wimp! scared! what do i do!How do i break up with him?
wait til after exams......drop little hints here and there so he will suspect things arent perfect..then when the time is right just do it! make yourself happy......good luck!How do i break up with him?
Wait until he is done exams, that is one small exception you can make. But you can distance yourself from him to kind of hint to him what you are planning to do, that way he won't be totally surprised when you do it. If he wants to see you, just say that he needs to concentrate on exams and not on you. Then after exams, sit him down face to face and tell him that you don't love him and you don't want to lead him on anymore. Don't be afraid of anyone hurting you, having his friends fight his battles physically or with words is cowardly and he won't want that kind of reputation.
