I don’t think the problem is with her. It’s him who left the house and went without even discussing. She was very clear with him about taking care of her mom before marriage and conveyed the same to him to which he agreed. It’s not her fault if he’s fickle minded. She even was ready to stay with him despite him not helping her in any way when it comes to household chores. What can she do if he leaves all of a sudden and not respond to calls or messages?
