<human>: We have been together for nearly 4 years. The two of us have had our ups and downs but we love each other very much and have an overall great relationship. Every now and then an argument will seem to pop up out of nowhere and it'll take days to recoup.  
Tonight I was starting to geek out a bit and she began interrupting me to say she understood. But it wasn't really what I was trying to say. She interrupted twice, I tried to bounce back and she gave me a look so I said "ok, I'll shut up"  but she insisted I finished. Uncomfortably I did half heartedly and she said "so basically everything I just said"  so I started saying why it wasn't really what she had said and things really got heated .  This escalated and continued for awhile until I finally explained what I was trying to the first time around. And it seemed that it settled but she responded with,  "well who kept interrupting who?" to which I responded "you kept interrupting me" and she began to try to justify herself but started yelling and stormed upstairs screaming how I'm wrong and I'm a d*ck and I'm not to sleep in our room or talk to her the rest of the night.  Also I've been told I'm not invited to go see our family and friends this weekend with her. 

I don't want to argue. But I don't think I did anything wrong and I don't want us to spend our lives getting into these stupid fights. I feel like I need to find some way to address this without starting another fight.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My fiance (30f) and I (28m) get into nonsense fights where she gets burning angry and I need to find a way to get it to stop or address her anger without more arguments.
