Over many years of marriage I have developed Bitterness towards my in laws. Lot of small, minor,silly issues.I wish I hadn't developed that kind of bitterness towards them because they are the most important human beings for my husband which I understand. He says he doesn't care how good or bad I am towards the world but I need to be nice/good to his parents. His expectation is valid but I'm not able to fake my feelings I have towards them. The damage is done in the relationship I had/have with them to en extent where I have confessed to them I'm not comfortable with the set up of staying with them in the same house. I'm not getting into details of the issue but what's troubling me is "what would help me undo the bitterness I have developed towards them, is it even possible?" . I don't hate them but I cannot share my life(daily) with them. I feel suffocated to do that. All this has slowly started creating small spaces in the relationship I have with my husband . We are good otherwise. Fight /argument comes because of the fact "I cannot get along well with his mother n father who are both 75+"
