I think the flaws of every guy that I know that is dating, is the fact that they get involved too much on impressing the girl that they are dating. The guy forgets that sometimes all you need is coffee, laugh and great conversation to close the day. Impress them with the memory of the moment not the tangible objects. Those are temporary. You can give her a gift on occasions but even that will require a great memory to make it harder to let go.
