I (47M) and my soon to be ex-wife (36F) are still living together. We do have children. We have been staying in separate rooms. Been sharing the load pertaining to parenting and household chores. She has a typical M-F 8-5 job. I work a non typical schedule. Three week schedule of 8 on 3 off, 5 on 3 off, and followed up with 7 on 2 off. This schedule just repeats itself for the entire year. Also, my 8 day week is my on call week. So potentially i could be gone most of the week.Yesterday, she started nagging at me about various things. Outdoor chores, helping with laundry, dinner and such. She said she feels like she's doing 95% of the household chores. So I reminded her that I took care of dinner 3 of the 7 nights. I do my own laundry. I cleaned out the garage after the winter grime. Ordered a new deck belt for the mower and waiting for it to come in. Washed dishes, and various other things. Helped take care of the children. She obviously didn't appreciate my reply. I kept it short, to the point, and stayed on topic. But later she asked me why I was being so short with her. I wasn't completely honest, because I knew it would be used against me. I did want to say well, I don't appreciate getting nagged like I'm a married man without the benefits of being married. But chose not to stir up the hornets nest. But should I have handled it differently? As a man is I know I can be blunt and to the point, but I don't appreciate the lack of her noticing what I have done. What should I have done differently or said differently?
