I am so happy to hear you say that you are doing this for you. Let's think about this for a minute. There is not a damn thing he can do to stop you from losing short of sabotaging your food with extra calories or shoving food in your mouth and making you eat it. It is highly unlikely he will do either so I think you are safe there.
What if you were sick and lost weight? Would he be upset and jealous then? No. Well, maybe because you were sick but you get my point.
I say go about your business and drop the subject with him. He will see how great you look and will want to show you off to make EVERYONE ELSE jealous!!
I have a motto that I use that came about quite by accident in my business but it has carried forward to many other aspects of my life- YOUR problem is not MY problem.
I am a bit older than you (44) and have been married 20 years. About the time I turned 40 I realized that I just don't care what anyone else thinks. I think back about how my mom would embarrass me to death. Now I live to embarrass my kids too (14 and 16)
. I have finally reached the same point my mom did. She was living to have fun and didn't care what others thought and she still does.
Look at all the crazy old ladies you see, wearing the crazy hats, dancing around and just having a great time. They just don't care what others think! My point is, you will get to this stage too. Do what is right for YOU and don't worry about what others think. It is your husbands problem, do not let it become yours.
