He is the worst isnt he! I think she's reaching that stage in their relationship where you are so deprived and starved of what you really want and need in a partner - your self esteem and hope is so low, you almost start zoning in on the good stuff to mentally survive and cling on. You think 'I should be so so grateful for this' and it can be the most basic, bare minimum shite. I know I did this, with a similar sleepy, sloth like, second skin dressing gown man.
Like everyone said, plans now to do things on her own because she is deeply lonely, not from a result of having a general healthy desire to expand horizons and learn new things and be indeprndant - but due to sloth boys long term lifestyle and lack of a full life together. shes going in to survival mode. I think tbf she already does do such a lot alone.
I think go for the solo camping, candy. Maybe this is the year the light switches on and you wake up. Wasting your 30s on someone slugging towards a pipe and slippers is tragically sad mentally to recover from, he is not worth this. Resentment phase is next and its not pretty.
