Arguing a lot!!!

I’ve been in my current relationship for about a year and a half and it’s been hell these last 8 months. We seem to argue about the smallest things but mainly sex. I love him more than he gives me credit for.. I work 2 jobs and he do side jobs because we are in financial trouble. So here’s the problem, we argue so much that I’m not physically attracted to him like I use to be but I want my relationship to work. I’m leaning towards ending the relationship but I want to get advice on what we could do to make things better before I go to that extreme.
