Most Helpful Guy
talk to him in person or on the phone. Don't text. every woman that has broken up with me has done it via text, even at my age and that is just cowardly. Answer all the questions he has the best you can. Be truthful no matter what. It does not help to lie just to save his feelings as it will cause confusion when he is thinking about it later and the lie contradicts other things you might have said to him. Don't give him the typical woman "we can be friends" bullshit. men and women are not friends. and when a guy has dated, and esp if he has had sex with you, he doesn't want to be friends.

Tell him your not interested the way you once were because you have changed as a person. Break ups hurt just be honest. If your not attacking him personally but making it more about the changes in you, it should be less hurtful. You can't stay with somebody you no longer feel that connection with that's not fair to either of you. Sometimes people change and it's beyond anyone's control. Don't go back and forth or feel guilty or drag it out that will just hurt him more. Be honest.
