Nikaah & Marriage Issues

Using speech techniques to make one's spouse love one

Q: I would like to know if I can speak to my wife by implanting thoughts in her mind to love me without her realizing this consciously to improve my marriage. These techniques are taught in NLP Neuro-linguistic programming which teaches people how to use language to influence others by saying a sentence in a way where you are telling the mind what to do. For example, instead of saying you should love me, I said to her you can feel yourself loving me more and more now. Is this permissible for me to do?
