DH and I are both from a developing nation who worked hard and smart to get to the US and make a decent living here as engineers. MIL has always hated me and reduced contact with DH as soon as he married me, against her advice ( and fake suicide threat). After the birth of our first child we gave her a courtesy call and she expressed a desire to resume regular contact and a good relationship. Overcome by hormones and unicorn feelings, we agreed and started calls, skype sessions, sent her an ipad etc etc. A year later, I was (unexpectedly) pregnant with my 2nd and went back to work (insurance and need to save more) and she suggested she come over here so that she could babysit my firstborn at home and also help after the new one was born. We paid for her flight, shopping (for clothes, appliances, utensils) and she arrived at our home as a long-term guest. Within days she took over everything and deliberately crapped up the cooking so badly that I could eat only fruits , raw veggies, bread etc only. In our culture it's a bit disrespectful to cook your own food and eat when someone else is making it for the family. She'd just add hot spices to nuclear levels even after my husband requested her repeatedly not to, and refuse to relinquish the kitchen. She dirtied the entire house... stuff like opening doors with hands that had dirt in them, made the bathroom a stinky war zone and left veggies peels all over the kitchen counters and floors. She refused to use either the dishwasher (washed dishes incompetently by hand that led to stuck food and mixed it up with the clean dishes - I had to inspect them and put it in the dishwasher at midnight) or the washer( washed her shit clothes by hand every day and hung it up in the stinky bathroom mentioned before even after I offered to put them in the washer along with our clothes). She kept our child in the same diapers from lunch time to 6 pm because she claimed it wasn't "full" yet. She stored inconsequential quantity of leftovers in tiny containers all over the fridge for weeks and fed our little child stale,leftover food on two occasions during the time we were at work leading to stomach distress - she outright lied when we asked her if she had fed him leftovers ; we discovered the truth when a neighbor on a playdate told us that the food little dude was being fed was smelling. The final straw came when she nagged her way to the delivery room to watch me give birth when I was induced earlier due to a medical emergency and my older one was in her care. She brought my 18 month old to a delivery room at 2 in the morning, to watch me push a baby out ... as if it's a spectator sport. No care or concern if the kid would be traumatized by watching a birth and mommy bleeeding......
