My husbands father is in a nursing home and my mother is in a different nursing home. My husbands siblings live out of town. We have been married for 25 years and have done everything for them all our married life. When I say everything, I mean from shoveling 100 feet of snow, cutting 3 acres of grass, repairs on house, cleaning their restaurant/ nightclub, doctors appointments, shopping, etc. There is so much friction in our families because we have spoke up for help. Siblings now are coming in to help from time to time. Mother in law does not take into consideration we are trying to take care of everyday living while caring for them. When other siblings are in from out of town they are here to do for her. Mother in law plays them against us. They are resentful for having to take time away from work to help. My husband and I have asked for them to let us know when they are coming so we can plan time for us to no avail. We are getting burnt out with the load and I feel it's hurting our otherwise happy relationship. Please give us some advice.
