Help, Advice, and things better left unsaid...

So I have taken a slight cut back on the diet and exercise recently, but I have been maintaining my weight.
I have a gentleman at work that keeps checking in with me on my progress once to twice a week.
I explained to him that I wasn't really losing and that I was maintaining my weight just fine.
BTW this is a person that has given me advice that I "should" follow the entire time. I have usually just ignored him, because what I am doing is working for me and as long as it is working I don't really need the advice on things that I need to change. A helpful suggestion on a tasty low cal meal is one thing (really appreciate those), but trying to design my methods for me is completely another.
Any how, when he finds out that I am not significanlty trying to lose weight he starts to tell me that I can't give up, what I need to do to keep focuses, and what my end result weight should be.
Now I am trying to figure out when I appointed him and my goal setter, cheer squad, and dietition. Still can't.
Enough was enough, I and finally asked him "When did my target weight become your desicion? When were you appointed to be the person to make my health habits? Finally, when can I have that responsibility back to me all me?" (He hasn't talked to me for over a week).
Morale of the story, be supportive of those that you care about and have made the choice to change the health and diet, but resist the urge (strongly resist) to worry about our diets. We don't expect you to change your meals when we're coming over to dinner. We can figure it out if we have a high cal meal or eat too much. Please continue to be who you are that is why we love you. It's when you become over bearing and start worrying for us or think that you have the right to make our choices for us that it crosses a line.
I sincerly mean this in the most loving way that I can, but sometimes the lines have to be defined so we don't offend you and you don't offend us!
