I know how that feels. I have a friend who always does that. When I have a problem, I appreciate the fact that he wants to help, but he never does. I don't ask him to help me, so it's sometimes annoying that he promises so many things, big and small. For example, I was frustrated because I gained weight. He'd say he'd help me, send me recipes and check on my progress every week. He never even sent me the recipes. He says so many things like that. I hope he'd just stop.
