I feel like Victoria has put up with a lot of bologna from Billy. This time with his infidelity knocked her for a loop. How much more can she take from him. Her support in him throughout Delia's death, she was 100% there for him and he found more comfort in Kelly (who gave him an emotional connection due from their children's death), who really was a stranger to him. Vicki feels betrayed and dejected from her husband whom she has many years of history with, and Kelly Who had weeks. Hurts a person to the soul. Hard for her to forgive and forget. ( once again.) in my opinion Vicki with take him back, after she licks her wounds. ( even though I feel with the new Billy there really is no chemistry at all.)
New Billy was trying to fill big shoes, even though he's not that bad of an actor, the writers really throw him under the bus with his story lines. 1st no chemistry probably because of his young looking appearance, and thrown into a already intense s/l, he never caught up. To me it was up to the writers to feed him into each scene, give him great lines, make him believable, and they didn't pull it off. Sad, since we miss the old Billy who connected with each line, had the chemistry, and knew his role as Billy with Victoria.
Feel now Stitch and Vicki have much more chemistry then new Billy and hoping they become a couple over Billy. But as I said before she'll probably go back to Billy her emotional addiction. Boo
