I pretty much always tell my boyfriend what's wrong when he asks, but there are times I don't feel like talking about it, or I personally believe the reason is stupid and don't want to bother him with it. It's not because women are manipulative and like watching you suffer, maybe they just want to forget somethings wrong and spend time with you :)
It may shock you to learn, but females are also human and have human emotions. Sometimes we get frustrated over silly things. We get called crazy for being upset over little things, so maybe we find it embarrassing to share those things sometimes.
But moreover, I really just don't like focusing on negative things. If I'm in a bad mood, I don't want to talk about it, I want to try and have fun and get over the bad mood!
Yes, I do it. Unless I'm being overly emotional and irrational due to PMS. Sometimes a woman doesn't open up when she feels like her feelings won't be validated or that her thoughts matter. Men don't always get the gold star in communication :)
