Flight in relationship

I want to make my relationship work so bad. But i just feel exhausted i can't do anything anymore. everything feels so forced. There are times where we are perfect for each other but when we argue its bad, we end up crying. i don't know wjat to do, I dont wanna break up i just want to fix everything and have my happy ever after.I am seeing a therapist the past 6months and i hope it will help me improve my thinking and my relationship. For me thats a serious decision because it affects my everyday life.
