Most Helpful Guy
It is ALWAYS a mistake to say that you love someone because it is expected of you. Now, not only do you not love him, but you have lied about your feelings and he might think it was part of a conscious and deliberate plan to manipulate him. Telling him will only cause harm and, while I never espouse being dishonest with a significant other, I would not tell him under these circumstances. Give the relationship a few more months to see if the feelings develop within you and, if they do not, it is time for you to move on.
