I dont think you are bad. My wife and I have broken up after 26 years and my dressing had nothing to do with it. She has become a different person. I was the one who wanted to keep the marriage together at all costs, and she didnt. She too is going through perimenopause...or perhaps menopause. She refuses counselling or medication or anything like that. She was shrieking at me over things like taking the trash out, doing the laundry wrong, leaving my socks in the bathroom. Not yelling. Shrieking. Turning purple, spit flying, screaming at the top of her lungs.
I honestly dont think your dressing has anything to do with anything in your marriage, honey. Im not sure you are going to get this worked out before your trip...even if you did, im not sure thats your long term goal here.
I do hope you take it easy...have fun...Im not going to lie...since I moved out my life has changed alot...some good, some not so good...im in limbo in alot of things and i miss my kid like crazy but its now MY life. Its not hers. Maybe it will help to keep that in mind...
Cheers
