I'm constantly trying to give this advice to someone in my own family who frets about something similar. You just don't have that kind of control, just as you don't want someone to try and change you. If you want things to be different, you have to figure out how to change things on your end to make yourself happy. Now, if it's a marriage, that's more complicated. But I think the sentiment is still important. At the core, nobody should be trying to change...anybody.
