Symbolic meaning of unopened package in Castaway?

he held on to it because it gave him hope of one day being able to deliver that package. When he got home he came back to discover his girlfriend had moved on and got married. So, he decided to deliver that package and found the person wasn't home. But as he was leaving he noticed the truck with the woman inside and it had the same symbol on the truck as it did on the package, so he knew the package belonged to that woman. In my opinion, the ending with him seeing the lady in the truck meant a new beginning for him, possibly with this new woman.
