GAG wise words from both you and Antonia. I agree about relationsihps where one person does the heavy lifting.
Have you heard about the concept of freeloaders, renters and buyers in relationsihps? Freeloaders speak for themselves . . .renters bail out when the going gets tough Buyers invest in relationships long term.
I think that MLC turns these people into renters, and then freeloaders - they regress. Returning to being a 'buyer' takes effort.
It is a stressful time for you both, in different ways, and a testing one . . . .
