My W does the exact same thing about me helping her. She won't ask for anything I used to do - like you said, practicing to be alone. Last night I put my hand out to help her out of her chair, been doing that for years - she stated "I can do this on my own" or something to that affect. She is detaching from the relationship in my viewpoint. With this being said, at least it gives us a baseline of when we do get a baby step. My W is still in the house - and it is TOUGH my brother. As my posters tell me, give her the space she needs, we need to detach.
As far as weight loss - I lost 30lbs in 4 weeks, have now lost 36 lbs. I am only a little over 6'2". I rarely eat. Get some protein drinks at the store or some protein bars. You need your physical strength as well as your mental strength if you are going to fight this battel and make yourself a better you. I think since March 17th, I have only eaten 4 complete dinners, last night, I actually had a mac and cheese (good old Trader Joes). But I am where you are, it is not that we are choosing not to eat, nothing tastes or sounds good. I have been using dinner time with W and kids as an opportunity to try and eat. I eat very little, but just having conversation is a good thing.
Take care,
CBK
