Men have a rubber band type behaviour, i.e they are intimate for sometime, then they have to go into their cave before they can come closer again like the more a band expands on one side, the stronger it comes back.
Women have a behaviour called - "going into a well". They have a wave like behaviour. When are going to the peak, they feel happy and ignore any issues they have. Once they hit the peak they begin to go down. Then their confidence level decreases and feel insecure. They may become reactive during this time. If a man tries to fix her during this time, it will backfire. They should reassure their women of their love and be there for them. They just have to listen to their issues and once their self confidence hits the bottom, they will again feel good about themselves and come back lovingly.
What if both happen at the same time - Then it is ok for a man to say that I need some time, I will come back to you. Women may ask what are they getting by this - They are getting a more attentive and loving man if they allow them to be in their cave for some time.
