well she may get the wrong idea of you. it's really weird, you have nothing to do with her.
why help her as opposed to anyone else, just because she's the daughter of your ex wife? You didn't raise her, you never knew her, she's not your kid. She has no more relation or purpose to you than my college girlfriends kid.
If you just want to help a stranger for no reason other than the goodness and kindness of your heart, sure, go for it. But you wouldn't be doing it to any random woman, and I just don't see how her being the daughter of your ex wife has much to do with you
Also I would normally not be butting in to such a personal thing going on in someones life, but your thread directly solicited peoples opinions on the matter, so that's what mine is.
