My DM is miserable. My DF is retired, does bugger all and is a boring old fart. He's 10 years older than DM. They've been married 30 years. He used to work a lot so they enjoyed their time together but now he doesn't show much interest in even talking to her, they don't go out or do things together, they eat meals in silence, he's incapable of changing his routine and doesn't really consider her. He buys her a birthday present but it's something she wouldn't want in a million years and he expects a pat on the head. She's not quiet about what she wants or needs either. I don't know how to support her, I don't think she wants to upset the boat by leaving as she's not good with change either, but it's hard seeing her miserable. Advice please?
