Tell your husband that there isn't anyone else at the gym...it's just you've developed a fetish for inflicting pain on yourself!
Going nuts eh? That is why all those things you've learnt doing your weight loss journey are now going to be vital for you to get through the toughest part. All those skills and insights arm you for the sheer slog of the last bit.
I know what you are going through. Towards the end of my wait loss journey, I said to my wife that I just wanted it to be over. She took it to mean that I was thinking about quitting and started to comfort and encourage me to continue...but I corrected her misunderstanding. What I had meant that I wasn't thinking of quitting but that I was just tired of the constant jogging to that finishing line...yet the closer I got (with more and more effort) - the slower the progress.
Nearing the end of my journey I was usually exercising for at least three hours a day (one hour exercise bike, one hour jogging and one hour swimming), it felt as if I didn't have a life apart from weight loss. The last two months was a virtual stand still weight wise. I would shift a few kilos and then put them back on. I was tired and worn (know all about falling asleep after exercise - not helpful as it burns less calories!). I knew that in the end that I would have to dig even deeper and finish it off with all I have. I was able to identify that my snacking had increased too much (I was so tired that the body was craving the energy/sugar of the fruits)...so I cut them right down and worked my butt off. Within a fortnight I managed to knock off the last 3 kilos.
When I stepped on the scales and it registered my goal weight...I didn't jump for joy or cheer...all I said was - "finally".
I was well and truly over the weight loss journey by the time I had hit goal.
The good news is that maintenance is such an easier caper compared to reaching goal.

I know it is hard...but as you have discovered...it is worth it!
