Wife Threatening to file divorce and demanding family property share immediately

Hi, I moved recently back to my parents' home after a gap of 12 years (having lived away with my family since second year of marriage) but with their consent (as both in their 80's; property being my father's own which he bought from his share of my grandfather's original property) including that my own financial condition also a bit challenging in terms of job-shifting etc. However, an year-and-half passed, challenges of living together are more and more complex (as both parents are still able to manage daily chores but space a big challenge due to house's design and their conventional attitude towards shared house spaces like kitchen etc). Hence, due to multiple challenges of space constraint, shared costs and difference in attitudes in the midst of child-rearing, my wife keeps threatening to divorce (though my father has made related property-will with sufficient share for our sustenance amongst sibling share). Also, many stressful situations due to unexpected tempers, including in front of our kids, it is becoming difficult for me though I have assured her to keep all options open (even to move out again, to which she has some reluctance due to some logic of her own and the accompanying financial burden at this point of time). I am trying my best and want to keep the marriage together but she insists it's never going to go right. Request help as I am really stressed and impacting work-life though I am currently the sole earner for my family. Thanks for your help me manage this tough situation for all of us. Regards,
