The first reason why the man is giving you a gentle and soft words, lies in its inferiority complex that may occur as a result of not quite the right education. Perhaps the family of your young person was not accepted to openly Express their love and emotions, so the man would keep a low profile in relation to its second half. If you try to instill in him a positive attitude towards compliments, most likely, it will not give you the desired result. With such problem it is better to go to a psychologist.
If your man just doesn't like to talk a lot, and is notorious silent, hardly you will wait on him gentle words and tenderness. To change the character of a person, you can not, therefore, if you do not like this guy, change it to more talkative, just remember that the secret to happiness lies not in the compliments.
Another reason for the lack of gentle and loving words from your beloved representative of the stronger sex is in his lack of feelings for you. Previously, he was gentle and considerate, but now has become rigid, most likely, love or not, or it's gone. When people no sincerity, passion and togetherness, affectionate words and compliments from men can be expected. He won't say something just to please you because to do it is absolutely do not want. Talk to your lover and ask, not cool if his feelings for you. Maybe he will say that in fact your feelings are in vain, and his apparent indifference due to the many problems at work or some other factors. Do not rush to destroy the relationship as you can because of the stupidity of losing a decent man.
Think about what the absence of sweet words can be caused by some negative events of the past. Maybe your young man once met a girl, tried to be gentle and tender with her, showered her with compliments, and she mocked him, taking the gentleness for weakness. Such behavior could provoke the emergence of new complexes and a dislike of anxious words. Explain to your man that you are missing the warm emotions and the banal compliments. Tell me you won't laugh at his feelings, and, conversely, will appreciate this positive impulse and manifestation of the delicate and sincere love.
