I feel the same. I say that as someone who has lost 7.5 stone on Mounjaro.
I know how hard you have worked, unlike at least one other poster on here.
Congratulations on your loss!
It's a shame your partner hasn't noticed, but maybe he has rose-tinted glances of your appearance, like my DH? He has/had no idea of how much weight I had gained and that I had weighed 228lb - which is more than he's ever weighed. I am so lucky that he just adores me, whatever my size.
In the beginning I was so proud telling him that I'd lost 20lb, 30lb, 40lb. When I got to 80lb loss, I think he started to twig, but didn't want to say or embarrass me I stayed quiet from then, just said I was approaching my goal.
I am now at the weight we got married as I lost over 100lb in the end, I'm just too embarrassed to tell him that I lost 3 figures!
