I'm 5 2 (almost) and if I was 72kg I think I would feel overweight. More importantly than losing weight you should focus on being fit and healthy. Do you feel strong, can you run if you need to, do you get enough exercise and eat healthy food most of the time?
If the answer is yes to all of them then tell your DH to take a hike but if you think that you should be fitter then maybe look at some small changes to increase your fitness.
