SDFgirl ....
If you think the packrat in your DBF is going to change ..... then I want to know if he has any sisters!
Seriously, DW and I have been married almost 10 years. Most years have been difficult. There have been some reasons for this on both "sides". DW is a HUGE packrat (she has Woman's Day magazines from when she was 19!), and is late (for any one thing) about 95% of the time, and is, shall we politely say, "retentive" about the way some things are done around the house. As for myself ... I HAVE to be early for everything .... and "my stuff" (clothes and other items/keepsakes of mine that I hold dear and will take to whereever we move next) could fit in a Cavalier.
That said, DW is gradually getting better and I give her "kudos" when I notice.
Gosh SDFgirl, if BOTH of you are just able to say "I'm sorry. I didn't know. What can I do to help?" that will immediately stop 90% of any arguments you two will have.
Good luck and God Bless.
