Arguments in Relationships

Shannon
Ladies, help! I'm truly struggling with the arguments in my relationship. I can't tell if they are just healthy arguments or signs of an unhealthy relationship. What are your experiences and what do you suggest for me to do in order to figure this out? 
***I have been with my boyfriend (seriously) for a little over 1 year. We were very close friends for about 5 years before we decided to date, and dated for 6 months before we became serious. I am 17 and he is 19, approaching 20 next month. I am a junior in high school and he is a sophomore in college.
