I'm very sorry this person is having to suffer all this crap, but

If you put out a lot of energy, for "free", then you often get shit in return. If you don't take responsibility for what you are getting back for all your hard effort, things can easily go pear-shaped. This seems to be one of those mystical laws of the universe. I'm not saying you should be selfish, or charge big bucks for your time. There are plenty of ways for people to give something back, and you need to make sure that is happening too.
