Is it possible to dump your boyfriend/ girlfriend by cheating on them?

To be fair to Penny, she's the adult and her mom is acting like the unruly teen. Penny's the one doing all the chores, picking up after Pam's messes, and getting nothing but hostility in response. She's probably the most mature of the bachelor(ette)s. And Maru's a Nurse. Hailey lives with her sister, but there are no parents in sight.

Will agree with you about Abigail, though. Also Alex and Sam and to a lesser extent, Seb (who at least has a job).
