Women love to communicate, and you will always find them encouraging their men to do the same. Unfortunately, most men don't realize that a woman's idea of communication means actually listening to what she has to say and understanding her as well as relating to her problems without judging her or providing unwanted advice.
It's no secret--men and women have very different communication styles. Women primarily talk to explore their feelings, while men primarily talk to find solutions. But if you want your relationship to work, you need to learn how to listen to her properly and learn what not to say to your girlfriend.
For women, talking and sharing are bonding experiences which help them build relationships. They learn how and who to trust by communicating and paying attention to the smallest of details. Whenever your partner speaks, listen carefully, make eye contact and ask questions about her feelings. Tell her you see how the situation could be upsetting, difficult or frustrating to her and encourage her to open up without offering any solutions or trying to change her feelings.
Try not to be sarcastic as doing such will insult her intelligence. Give her your undivided attention and remember--you don't have to agree with your partner, just listen and try to understand. Make sure that you're not watching the game while she's trying to discuss your one-year anniversary together. Most importantly, listen for clues in her speech, e.g., she tells you that there isn't enough sex in the relationship. Translate that as she's really telling you that she wants more of you. Better intimacy is a good thing, right?
When you learn how to properly listen to a woman, she will feel understood, respected and reassured and it will lead to fewer communication problems in the relationship. If you value your relationship, you should listen to her. Otherwise, you run the risk of having her find another man who will!
