Well the thing is, this is out of the norm for you and he. BECAUSE, normally, he DOES call/text you and you said he is a very responsive... phone person and has even been upset with you... when you didn't call him to say hi. And that normally, HE DOES call you at least once daily, just to say hi.
SO that is why, this has you... bothered. It is not his norm. At all.
Thus, the concern is there.
If my Hubby were away... even if he goes out after work, he calls me. Just to let me know of his ETA, back home.
Or if he is going to be late in getting home or if his plans changes. It is just courtesy and caring and letting me know what the hell is going on... since I am home with the kids.
My Husband calls. Even if he is in a bar with friends after work.
You did call your Husband first, Before you tried the friend. You tried being reasonable. You did what is pretty normal. But your Husband's reaction... is not normal. Not his norm.
Thus, the concern.
Frankly, I don't know what is the problem.
Sure he is on a trip. But a Husband can still call.
Gee and you are home with the kids. What if something happened???? The common sense thing to do, is to call your Wife back or answer the damn phone when she calls.
I would be irked too.
I don't blame you.
This is.... strange?
The thing is, even if on 'vacation' or a trip with buddies, it does NOT take a lot of effort to just call home for 2 minutes. Geez... anyone can find time, on a trip, to do that.
My Husband went away with my daughter to Europe once, on VACATION.. HE called each day, to let me know how they were and what not.
He is a Husband. He is a Dad. And I was back home with my son.
Vacation or business trip...a guy CAN call home.
It is not much effort to do that.
It is NOT out of sight out of mind.
