Hugs. Oh dear feels so sorry for you as it’s an awful feeling not to feel love from your spouse. Firstly, she’s the blood mother and secondly her best “advantage” over you is playing the victim card of losing a husband and being lonely and my DIL still acting like this (possibly what she has been telling your-husband-her-son behind your back) I agree with others that she’s jealous and scared of being alone and so possibly trying to distant you and her son, so that she can have her son back. Unfortunately she won’t understand that this is causing her son’s marriage and her grandchild’s childhood. Not good for children to grow up hearing seeing parents quarrelling and grandma finding faults with mum?! I’d prioritise my child above all and talk things out with my husband, from the perspective that it’s not healthy environment for the child and then move on to say that how it’s badly hurting you emotionally. However, if he is unable to reason things out and blindly side his mum, I’d move out back to my parents place. You too is someone’s else daughter so why should a 60yo treat you like dirt and let you get scolded by your spouse.
