That might be part of the issue if your other jackets are too short. You'll need to get used to something that is noticeably longer, and I'm sure you will.
Making strong recommendations about jacket length from a photo is tricky, given possible image distortions and people's different principles. The number of times people on SF make this judgment based on a torso shot...hmmmm.
For me, the "principles" of length are: (a) cover (at least almost all of) the seat; (b) pleasingly divide the top and bottom (visually lengthen leg while maintaining "solidity" above) and (c) balance the hem line wrt the hand. But aside from (a), everything will be relative to one's aesthetic as well as the style of jacket, the feel of fabric, seasonality etc. That's why I think there's a range for each individual, not some hard value.
In the future, I'd just stand a good distance from a full length vertical mirror and ask yourself if the position of the jacket hem is aesthetically pleasing to you and, of course, to your wife. Then tell any dissenters to, well you know...
