I think these two became such good friends at the end of BD. The comradeship between them in the clearing as as a family unit now is really nice. Jacob now respects Edward as a person now, rather than a "reeking bloodsucker' or "leech" and Edward is proud to have someone as part of his family who has grown up as much as Jake has.
The way they are so comfortable around each other is so good and how their shared love for Bella was the cause of the friction in the beginning, which could finally be resolved when Jake found his own and how their entire family has grown and strengthened as a result.
