Why can't my Metta goodwill transmit to alleviate my partner's depression?

I meditate on Metta in order to relieve my stress, though I specifically apply the goodwill to my partner with the hope that it will alleviate his existing depressive condition and anxiety. I would like to understand whether my positive mind is capable of really affecting theirs. Is it scientifically possible that my meditative state can generate an emotional contagion to assist him or is this merely a desire to control the outside world that is bound to disappoint me?
