i felt bad when i couldnt get my daughter the gift she wanted
Oh, that's got to feel rough. It's not quite the same, but I've felt similarly when I couldn't get previous ex-girlfriends gifts during holidays or their birthdays or something. But I'm sure she knows you love her anyway.
yea        .. it happens
It does. Feeling bad about it is enough to show you care about her, which is something, paradoxically, to feel good about I think. Just keep being a good dad to her. :)
