How do you deal with constant nagging?

[Gandalf]

I have been married now for just over five years and one thing that has really started to bug me is the incessant nagging. Since coming back from my holiday, the nagging is something that has really begun to stand out. It's all the time now. Honestly, anything I say right now gets turned into a verbal sparring match. I will say something, anything, and it will get turned into WW3. The same thing happened today. I simply said that I didn't want to do an early morning company class (starting 8am) and would much rather just work my regular teaching hours (between 10 and 6) and immediately she was on me calling me lazy, saying that I am useless, and telling me that she will never find me extra work again. Blah, blah, blah. A lot of histrionics over nothing. This time I put my foot down and simply told her to stop talking because I was just not in the mood for another row. Thereafter I simply ignored her and she stormed off to her room and here I am looking at a nice quiet night in the living room. I'm not complaining.

Ever since coming back from holiday she has been like this. The holiday was quite nice actually, but faltered a little towards the end which I had put down to PMS, but it's been getting progressively worse ever since. If I complain that it's too hot, I am always complaining. If I have a drink, I get called a drinking machine. If I wear a nice shirt and accidentally spill some dinner on it, I am in the doghouse. Today I went to work and my umbrella got stolen. I had to come home in the rain and my shirt was creased and drenched. It had been freshly ironed so I hurriedly put it in the bottom of the washing machine in fear of being accused of abusing my newly ironed clothes. That's just sad really.

One thing that annoyed my wife is that her company offered her a six month position in the UK and she asked me to drop all my contracts and just fly over there with her and do that. But I put my foot down and said no. I mean, no way will I just jump and leave like that. Korea is no heaven, but I have my responsibilities and ties here and to be honest I am more than settled. Maybe this is her sweet revenge, but if so it is extremely childish and tbh, I am getting towards the end of my tether with the whole shenanigans. It's not the easiest of things living overseas and if your supposed partner is then also trying to make everything you do so difficult then it leads to a lot of misery. I guess I'm just not very happy right now which is a shame because I really enjoyed my holiday and have come back quite refreshed. I haven't mentioned politics once since coming back!

So a thread about being nagged at and being in the doghouse. What are your experiences and how did you deal with it?
