Relationship Advice

My boyfriend and I have been together 3 years. He lives in New York and I live in Florida. We are currently in the process of looking for a place together. We love each other deeply. Our relationship is pretty solid. Only problem is whatvwe argue all the time. I know couples argue but I'm starting to feel like that's all we do. I have pretty high anxiety and sometimes get panic attacks so all the arguing literally can physically hurt. He knows this. I stay pretty calm during our disagreements but I think this makes him more upset. I'm starting to think if it's best for me to leave. What should I do?
SN: My boyfriend and I met at 14. We are now 27. We dated then, growing pains kind of stearded us in different directions but 3 1/2  years ago we found our way to each other again. Always felt like this relationship was meant to be. Just not so sure anymore. 
How do I fix this? HELP!
