I just hate that. Some people only come around when it's good for them or they want something.
My inlaws used to live two houses away from us, they never once called and asked if I needed anything from the store when I had surgery on my feet, and they used to drive by my house to go in and out of the development. My SIL also called me when she needed me to babysit in the summer so she could work, but not once they ever offered to take any of my kids . I don't do for them anymore, my inlaws passed away and my extended inlaws live three hours too close to me, I haven't talked to them or seen them since the parents passed, nor do I plan on seeing them either.
I'm sorry you have to go through this Pembo, I have friends here who care more than my dh's family do, I can count on my friend always as a backup in case I need her , and the same from me to her.
You have enough on your plate now, think of yourself first.
Best of luck to you my friend , and prayers going your way.
