The Young and the Restless (Y&R) spoilers reveal that Jack Abbott (Peter Bergman) and Diane Jenkins-Abbott’s (Susan Walters) relationship will land on shaky ground. Diane and Jack vowed to love each other for better or for worse, but they may struggle to survive the ways their marriage will be tested.

Y&R fans know Diane has already had some issues with Jack serving as Nikki Newman’s (Melody Thomas Scott) sponsor.

The whole arrangement left Diane worried about Jack’s old pill addiction and the possibility of a relapse.

Now that Jack has slipped like Diane feared, she’s going to be outraged.

Although Jack will act like he can just get right back on track with his sobriety, Diane won’t be as certain.

It may not be long until Jack’s needing another fix, so he may score more pills and dig a bigger hole for himself.

Jack could spiral out of control even further if he’s not careful and push Diane away in the process.

Meanwhile, we’ve got Tucker McCall (Trevor St. John), who doesn’t seem like he’ll be able to handle it unless he gets that engagement ring on Audra Charles’ (Zuleyka Silver) finger.

Since Audra has been shutting down Tucker’s marriage plans, could she ultimately push him too far with her constant rejection of the idea?

Tucker is known for having a hot temper and making impulsive moves as a result.

It’d be interesting if Tucker had a fight with Audra right as Diane and Jack’s marriage threatens to fall apart.

Diane and Tucker don’t typically get along very well, but it’s easy to imagine them commiserating at the bar about their romantic problems.

There could be some blurred lines when it comes to bickering and flirty banter.

We can’t forget that Tucker and Diane have hooked up in the past, so there’s no reason they can’t do it again! One thing could lead to another and land Diane in Tucker’s bed at some point.

It could lead to an affair or at least a one-night stand that Tucker and Diane might try to cover up.

Will Diane’s marriage trouble drive her to find some passionate relief with Tucker? Could Tucker turn to Diane after his Audra frustration boils over?

The Young and the Restless spoilers say bad news could be brewing for multiple romances on canvas, so we’ll bring you predictions on all the turmoil and updates on any major story developments.
