How do you tell someone you love them but do not want to be in love with them?

You don’t have to if you don’t want to. You knowing that should be enough closure for your own mind. If you love this person, but you don’t to, or you can’t fall in love with them, what’s the point of furthering the relationship? Don’t force your feelings, or feel as though you’ll someday feel it, because most likely if you haven’t felt that way now, you won’t ever feel that way. All this person needs to know is that you love them. That’s it. You don’t have to confess what you feel. Some thing are better left unsaid. Unless this person asks you, “are you in love with me?” then you should tell them what you just told me. You’re not a bad person for not being in love with a person who is in love with you. It just means that it’s not meant to be.
