Wife told me she wished I would just Die

There are two sides to every story, and I refuse to play victim here so I'll be fair. I'm 40/m I've let myself go some over the years. I am 6 foot 3 280 pounds. Hypertension and just barely crossed the threshold for diabetes on my A1C.

Wife makes jabs at ny weight to "motivate me"...talks about my belly etc which i resent. After child 2 we have slept in separate bedrooms die.to my snoring and she's a light sleeper.

She's a great mom, and keeps nagging me to go back to the doctor. I plan on it but want to lose weight first and get off meds.

This morning she is nagging me about sleeping until 8am (she goes to bed at 8 pm I go to bed at 1130pm on weekends) Then she started in on something else and to my fault, told her to shut up in front of my 3 and 5 year old.

She looks at me and said "I really hope you die soon". To her credit she saw the look of horror and took me to the bedroom to apologize and said that she can't believe she said it but maybe my un healthy lifestyle and worry for me to not be around my kids made her say it. It actually has put me into a depression. I feel worthless and she keeps acting more affectionate than she ever has but it only grows my resentment. I'm not sure what to do.
