<human>: I am dating a girl I want to settle down with. She is actually the first girl that makes me want to get married. The relationship is almost perfect except we have one big issue. 

Every few weeks we will be talking about something (often politics) and it will get me riled up resulting in a fight caused by my arrogance. I act like a jerk and make her feel bad. I need to make a change or this relationship will be over. She deserves a better boyfriend.

I'm ready to make a change and become a better person. Like I said she is the one, I wouldn't be able to live with myself if I lose her. It's entirely my fault and the relationship is perfect otherwise. I need some advice on how to be more humble and relaxed.

Can you summarize the given text in a few sentences?
<bot>: I'm destroying the best relationship of my life by being condescending towards my girlfriend over her beliefs. How can I lear n to be more empathetic and not get riled up over things I'm passionate about?
