Maybe think about whether there's a deeper reason for these rows. We sometimes brush over occasions when people have REALLY offended or upset us, only to blow up at them over the slightest thing.
Another tip is one my mum gave me prior to my first 'grown-up' holiday with my sister. She said "you're stuck with each other's company for a fortnight and don't want your holiday spoiled, so if you feel her getting on your nerves, just count to 10 before you start shouting at her" - it takes a little patience, but it does help.
Sometimes when your bf and you start arguing over stupid things, is mainly because something else is bothering you. Often the reason why my bf and I were rowing over the tiniest, stupid thing was before we were compatible and that our relationship now, wasnt the fun, going out, and cant be away from eachother relationship. We were just getting on eachothers nerves living with eachother, and too close for comfort. I was home all day pregnant and he was out all day working, and just got fed up. He wanted to relax when coming home from work, and I wanted to go out.
usually when you row about simple things, you either have pms or something else is bothering you. Try figure out what it is & work on that problem instead of getting into a illy argument. Instead of rowing, hug him, kiss him & so on, it IS MUCH better that fighting!
