Am I in the wrong?

Hey guys! My partner and I argue all the time!! We have more unhappy days than happy! We are always on and off but we both love each other alot. I dont know why we argue but we just do. The past week he and I have been getting along very well and everything seemed happy and blissful until last night. I had a flight to dublin and i asked my partner if he could FaceTime me properly and that it would make me happy so I could take a quick nap before my flight. He decided to tell me that I was starting an uncessary fight and shut his phone on me and fell asleep. I on the other hand stayed awake the whole time crying because i didnt know what i had done wrong or said wrong. I know i was pushing him alot to facetime me but only because i had my flight and we are long distance and seeing him makes me so happy!! Anyways he shut his phone, didnt wish me good night and then the next morning apologized but me being still upset about it argued with him for another 2/3 hours. He said i stress him out and look for drama but i feel like he doesnt understand why i was upset or that he only said sorry to shut me up. I feel bad now because i feel like i ruined our good streak. :/ was I in the wrong for being upset? And Did I push it too much? Or did i have a right to be upset? I feel bad for arguing with him but he knew facetiming would make me happy and I feel like the smallest things are such a big struggle with him. I love him alot I just hate fighting him.
