I have the heavy load around here with 3 kids under 5 and a husband who always travels for work (sort of a blessing, I do things my way, no one to criticize me). God bless him. He's a neat freak. And he will often come home from weeks on the road and within minutes comment on "some little thing out of place." I told him a million times not to do this, to no avail.
Once, after a firm warning from me before he got home, he tried not to say anything...about a crayon under the table.....a cheerio under the coffee table.....some mail on the table that hadn't been sorted...but I could see it bottling up. Finally it blew up over some backed up recycling in the spare bathroom. Mind you, I had warned him in advance, that because I was on semi bed rest with a late term high risk pregnancy, I was not going to haul the two kids to the recycling place for a couple of weeks and I would leave it for him when he got home. He of course said the right thing on the phone and said this would be fine. But when standing there looking at a few "bags of junk", he lost it.
It was probably one of the worst fights we ever had. After the fight settled, I re-pummeled him with how completely abominable it was of him to speak to me this way for ANY reason, much less about doing a "chore". How it was atrociously un gentlemanly-like and how he should really be ashamed etc. Not the way I usually speak to him at all, and I agree, mean for mean is usually not the best route, but in this case, he was absolutely not in touch with WHAT he had actually done or WHY it was wrong.
The clencher was that I gave him a consequence. I told him that because of his completely awful misbehavior and poor example it set for his kids, I would never again take the recycling. If he ever said one more word about it, I would find other chores to quit doing. To this day, I stack recycling in the garage for as many weeks as it takes, and the running joke is that he always takes it ALL when he gets home, and with a smile. If I catch him throwing his hands up or sighing when he sees the stacks, I say, "Oh, hmmmm, it sure would be a relief to store up all the trash in the garage too instead of taking it out twice a week...." then he laughs, because he knows I'll do it.
He also admitted it was not OK to give me a hard time about it (much like harassing you for forgetting goggles when you are the one who packs everything).
Keep this in mind, and take time to explain why his behavior is completely dastardly, but then go back to being your nice self. Maybe he will need a consequence or two (packing for the next two trips after being rude to you for forgetting something?), but also do really nice things for him, since honey gets more flies. My husband also tends to sit back and let me pack everything, I know I need to address it, I just haven't yet.
I am not one of those people who thinks of cheating all the time, but when I read yours, it did seem like he was looking for things to pick on, and treating you almost like he doesn't "like you". Interesting you included him not coming on a family outing at the last minute. Is this recent behavior? Keep your eyes wide open, stick up for yourself, and don't lose sight of the nice hardworking person you are. Don't let him turn you into a "poor me, my husband is so mean to me" person. You don't at all sound like that, but over time, this could wear you down. He is at fault. Take the reigns! It sounds like there are issues that need to be addressed, try to get him to talk.
