Not liking where this is going

This storyline with Jack and Jennifer is bs! There are so many characters to boost with a good storyline and instead they choose to disrupt Jack and Jen, again. And to what end for Gwen? How does this get revenge on Abigail? How does this destroy Abigail? What is Gwen's beef! Also, I heard the actress who plays Gwen was put on contract, which I'm definitely not happy about. I hate this character.
