It's true that when a women sits down with her partner to talk or express herself she will often motivate him into talking.
There are however things which can negate against this free flow of communication as if he feels that there is pressure for him to respond or that some kind of demand for self expression is being made he can go blank.
Sometimes men really do have nothing to say.
It is also true that should he feel forced to talk he may even become a force which seeks to work against you and this is obviously counter-productive to what you want to achieve.
A common mistake for women to make is that they can think their partner 'needs' to talk just because they do.
Very often men do not need nor feel any desire to talk and it becomes like and interrogation which he is going to rebel against.
Worse yet, a woman may think that because her partner is not talking that he does not love or care about her and the health of the relationship.
She may even punish or reject him in some way as a reaction to this.
The key is that men absolutely need to feel accepted just as they are.
By doing this you will fulfil one of their core requirements for feeling happy in the relationship.
If you do not force or put pressure upon your man to talk with you and instead simply appreciate him for listening to you, you'll find he will actually open up more and more in conversation.
Let your partner get used to listening to you a lot and if he is accepted and appreciated for doing this you'll find that gradually things will change and you will have the kind of feedback and interaction you are looking for.
