Hi, and welcome aboard. I noticed that many of the things you are doing to try to get a response out of your W are Acts of Service....are you sure that's your W's love language? If you are constantly doing these things for her, buying her things etc....and that's not her primary love language....then you aren't likely to get the response you want from her.
What I'm curious to know is....what types of conversations have the two of you had? What have you told her you need that you aren't receiving from her?
It does seem pretty apparant to me that her weight/diabetes has probably gotten to her emotionally...sounds like she might be depressed, in which case that can be a vicious cycle. Has she talked to her Dr?
I also wanted to point out something to you that you may not have thought of....all of this stuff you've been doing that in your perception is "motivation" might be, from her perspective.....pressure. I know you are simply trying to motivate her to do what's best for her health (mentally/physically)...but from her perspective...you good intentions might be coming across as "he doesn't like me the way I am, I'm not good enough."
