Unfortunately, his "addiction" will result in a greatly diminished lifestyle for you
in the end.
Someone who makes a conscious decision to not take minimal care of their own
health is, by default, going to dump their care issues on you down the road.
My mother did this with her smoking and drinking choices,
and I was the one left to deal with hospital and emergency room care,
daily visits, etc. to feed, shop, manage things.
Is this what you want long term?
My brother is obese also and just had a second knee replacement
and has had both hips replaced, many hospital stays, etc. for related
issues including heart, circulation issues etc. that his partner has had
to deal with for years.
Do you want this future for yourself?
I don't know if it is so co-depandant to not choose to commit long-term
to someone who refuses to care for their own health, and will by default
dump issues on their spouse down the road.
My own spouse is not caring for himself physically and is drinking too much.
His choice to not eat right, exercise, and continue to drink may be dealbreakers for me.
These are not "acts of God" but deliberate decisions for short-term gratification instead
of making choices to improve both of our lives. His right, but my right to say no.
I don't want to spend the rest of my life caring for someone who won't care
for themselves, even if I do love them.
I also have a right to love myself and make good choices for me.
It's a tough call alterity
