Wife left home

My wife deserted home leaving 6 year old boy with me. She is not willing to come back home and not even speaking to the kid. Her family is supporting her. She initially had fight with my mother, when I intervened fight turned towards me and things went ugly and she left house. For past few days she was finding reasons to fight as I brought my mother to my home because she had covid. My father is hospitalised for past 20 days due to covid, both my wife and kid were tested covid positive, only I was tested negative, I was handling things both at home and hospital. Iwas cooking, washing clothes, taking care of house and medication for every one, but still she had some issues and finally she busted over a small issue with my mother, started fighting with her, abusing her, telling her that's its not her bed, and my mother should cook food for her, and so on.. end result we had ugly fight, now she has left. What are my options, what should I do. I tried calling her, requesting her to come back even apologise for the fight. But still not responding. But I can't continue tolerating that she abuse my parents every now and then. I guess she needs some psychiatric help, I am willing to go for marriage counselling and her treatment is she needs any. Kid misses her but she does not wish to speak with him either. Please advise what should I do.
