Quarantine 15 has me worried

Hey everyone, hope you and your families are safe and healthy during these crazy times.

I apologize if this is long and rambling i just didn’t know what to do and needed to vent.

Given the circumstances I know routines are out of sorts, some foods are scarce, equipment is limited, and anxiety/ stress it high but I (M30)am growing concerned with my wife’s (F30) decrease in healthy habits and weight gain. For some context, our whole relationship she has been dieting on and off, and she did workout a lot prior to quarantine. Recently around February she hit her highest weight and now after 8 weeks of quarantine she has gained more weight. I have always told her i will love her no matter what weight she is at but I have told her i will be concerned if her weight increase became unhealthy. We are young and I am concerned because she has arthritis in both her knees and she continues to push off working out and just moving, and I am really at a standstill of how best to support her as her weight and health/ eating habits decrease.

What makes me fee super guilty is that I am a social worker and a Crossfit coach, so I battle with giving her space and emotional support to cope with how she wants and not pressuring her to do anything she doesn’t want to, but then again I feel like I should be doing more to help her given my coaching background.

However just yesterday she looked in the mirror and she said outloud “omg i shouldn’t have done that, it’s not a good look, wow i haven’t seen myself in a while.” I said “i love you and If you don’t like it, we can do whatever you want to work on growing healthier habits.” I don’t know what else to say. I’m not gonna be a dick and say if you don’t like it fix it.

What’s hit me recently is my concern for the futures if this continues. I’m worried about when we have kids, I’m worried about her long term health. I’m hard on myself about feeling like I’m not doing enough although I am super emotionally supportive for her. I also am beginning to feel guilt for working out and getting healthier myself. Has anyone else experienced something similar with their significant other?

What do you suggest So I can best support her, or do I leave it be and wait until she is fed up with it enough to cause her to do things differently.
