In a number of relationships, part of the thing I've enjoyed is helping someone get out of 'bad' situations and 'improved' their life in some way. It hasn't always worked but some of my previous partners have had big positive transformations. However at the same time I'm never sure whether is is exploitative or not.

I personally feel I'm fulfilling Dan Savages "campfire rule" (to make sure that dating you puts them in a better position than you found them) but at the same time I'm conflicted by whether its exploitative or not. On balance I feel it's all good providing both partners know what they're getting out of the relationship, but what do you think?
