non-verbal communication

I've been dating my boyfriend for a little over 6 months. He is my first boyfriend and I am definitely learning about all aspects of communication in our relationship. I am often the one upset or angry, so most of the time I will use body language and non-verbal communication. I am slowly learning that I need to be verbal with him if I want to get any feelings across. I will sit next to him and not talk for an hour, not talk back to his conversation, and he will STILL not know that I am mad about something. It really drives me crazy and I could relate well with the class discusion. We talked about how the message sent is often not the message recieved and this happens at least once a week with my boyfriend and I. The discusion really made me think about different ways to communicate with him about my anger and it will take away some stress. When I sit and wait for a response or expect him to know why I'm mad and he doesn't, it makes the situation worse because I don't get the reaction that I want. It is also important to remember that guys and girls communicate differently and my boyfriend and I are still learning about eachother's reactions.
