I don't think there is anything wrong for a man to help his wife with the bag. In fact, some days he can just help her not just for helping sake. And for other days, he can help her because the woman has so many other things to carry.
For the other part, I've read a lot of comments and my own might not be different from theirs so I won't write bout it...
Stay blessed
Thanks a lot brother, stay blessed too.
