The context of the following conversation is Austin's plan proved a little difficult to carry out, so Austin abandoned the plan altogether.:
Austin says I was so stupid that I thought I could win her love back..
The friend responds I told you that she had already moved on Austin, you have to let it go..
Austin responds The flowers, the candy, the money, none of it seemed to matter. I just abandoned the plan altogether..
The friend responds You can't win her back with that kind of stuff. You should have shown her affection and loved her, while you still had her..
Austin responds I know that now..
