My girlfriend thinks she is always right even when she is clearly incorrect. She has to have the last word on everything. I used to think it was cute, but I’m beginning to find it overbearing. I usually go along with her to save trouble but I feel like I’m losing myself. We have been together 7 years, and I have no intention of leaving her, ever. How can I change the communication pattern and get her to have more of a give and take attitude about life?
