Why do most girls hide their feelings with guys?

Well us women have an Ego too. We don't like to admit that something is bothering us. It makes us feel very vulnerable and that's a scary place for anyone. Every time I said nothing is wrong my boyfriend makes a joke out of it and says nah ah nothing means something LOL. Then I swallow my pride and spill it. Sometimes QUICKLY to hurry and get it out. The more you show support and don't judge the more she will trust you and spill the beans. IF she is healthy that is. If not then it goes deeper and I suggest move on.

Some girls play the let's play it off game and see how long he will keep trying you just have to keep trying to get her to let it out other girls really just don't want to talk about it they will come around when what is bothering them is kinda under the covers and they have taken care of it or can't handle it anymore....just keep trying to get it out unless there is anger or a strong feeling of independence being giving off....in that matter just back off and try to make her feel better buy her flowers, do the dishes, clean the house, give her a foot rub, make her feel good.
