Kudos to you, ilikemuffins, for doing your research and recognizing the differences in personalities. I don't know if things will work out with you and your girlfriend, but you're giving it your best shot with compassion and understanding.

I am an introvert. One of the closest, dearest people in my life is an extreme extrovert. We took personality tests together and we're on the opposite extremes. We can easily drive each other bonkers. My need for solitude can cause hurt feelings and the extrovert's need for connection and contact can trigger enormous feelings of irritation and feelings like I'm being smothered.

The extrovert wants to talk to me several times a day. Every day. With hours of non-work time dedicated to conversation and togetherness over the phone. Spend entire days with me when in town. I'd be perfectly happy to talk once or twice a week. Social interaction tires me out emotionally and physically and I'd like to spend shorter periods of time together.

My cell phone is turned off and locked in a drawer, used only when traveling. Repeated text messages annoy me no end and I refuse to engage.

As an introvert, I really appreciate it when my extroverted friends don't give me a hard time or get hurt feelings because I get tired of social interaction and want to spend some time alone in my room. I socialize with them and talk to them and spend time. But my limit of enjoyment is shorter than theirs. I try to contain feeling irritated at what feels like demands from them and in return I really appreciate it if they can avoid sulking or acting all hurt or accusing me of not caring because socializing drains me instead of energizing me. I don't know how or why it happened, but almost all my friends are extroverts, so this has taken a lot of negotiating!

If you can talk to your GF openly and honestly about this it will be a great learning experience for both of you. If things don't work out between you, you still will have learned a valuable lesson about personality differences and how to respect them. I wish you the best.
