Everything about him is irritating me!

I am currently on holiday with my hubby as it is our 1 year anniversary on the 6th of April. My mum and sister paid for a week holiday for us and I am feeling so ungrateful. Me and hubby are not talking to each other properly and I don't even know what the problem is. Every little thing he does is irritating me and I'm feeling like maybe I don't want to be married anymore.
