The word is "disingenuous" and means "not candid or sincere". If you ask her to tell you she loves you; that's putting your words in her mouth. That can't ever work. I don't think you want her to parrot your words?

I would look at how "like you very much and have a special place in her heart" is not what you mean by/want with "love"? Why does your exact word have to be said? Even if she said it, it would still be her word and not the same as your word because it would be coming from her and have her meaning behind it, not what you think and want it to mean, only coming from her.
