is feeling disappointed in her husband now that John “Finn” Finnegan (Tanner Novlan)

has let her down again. Finn’s decision to stick around at Sheila Sharpe (Kimberlin Brown)

and Deacon Sharpe’s (Sean Kanan) wedding sent Steffy flying into a rage.

Although Steffy wants to believe in Finn’s commitment to her over his birth mother, he’s making that difficult by opening the door to Sheila and more of her drama.

Steffy can’t take chances when it comes to Sheila since she’s seen her carry out too many crimes to ignore. That’s why Steffy has drawn a line in the sand with Finn on this bio mom issue.

Steffy has banned Finn from having Sheila in his life, but can she trust him to keep his word on that – especially after the whole wedding incident?

If Finn slips up once more, Steffy may have to try another approach to let him know just how serious she is about cutting off all Sheila contact.

B&B fans know Li Finnegan (Naomi Matsuda) is just as concerned as Steffy and certainly doesn’t want Finn to have any connection to Sheila either.

It’s easy to imagine Steffy and Li staging an intervention as one final attempt to save Finn from making a big mistake.

Since Steffy has been clear about her ultimatum, Finn has a lot to lose if he doesn’t push Sheila out of the picture.

Perhaps Li will team up with Steffy to remind Finn of that with a joint ambush.

Steffy and Li could get together in Finn’s presence to run down the list of all the horror Sheila has inflicted. Finn may think Sheila has changed, but Li and Steffy definitely don’t buy that at all.

Maybe Steffy and Li’s intervention could be a last-ditch effort to help Finn see the light about Sheila.

If Finn can’t start truly respecting Steffy’s wishes on this, Steffy might dump him – and Li could potentially disown him as well.

The Bold and the Beautiful spoilers say Finn has more Sheila-related difficulties ahead, so we’ll bring you more predictions on all the turmoil and updates on any divorce news.
