How do you deal with arguments?

My significant other and I hardly fight, but we did today, about something stupid. I'm feeling hurt, confused and lost. I seriously love him so much and I don't want to fight but yet I feel like I need to stick up for myself. With our work schedules we don't get to see each other except on weekends, which makes it more difficult to kiss and makeup. I know communication is key, we always get through things and it does take time... I'm just curious how some of you work through problems and conflict in your relationships.
