There's no nastiness where Rory is concerned, and I don't believe it is from Jake's end either. Rory couldn't take being shut out any longer and ended the relationship. They're trying to be friends, but it's tough because Rory did love him and still does to an extent. After their split she threw herself into her work but is slowly starting to tip toe back into the dating world which is driving Jake nuts, lolol. She'd stay on good terms with Maggie if Maggie allowed her to, but would completely understand if she cut ties and has daggers for eyes every time she sees Rory.
