Never a big Steve fan but he lost his ..angry personality with Carol which made him easier to take. I get that was part of his character and Carol/Betsy helped him with that and they wanted to restore it going into the Betsy relationship but man, it is hard to see him yell at people like Kim and she just takes it.
Going into this I think the Dobsons planned on having Natalie coming in and having a custody fight over Amy now that Jay was dead and Steve and her have a similar relationship as she had with Jay..the only problem was the casting of Natalie...the actress did not have that kind of sex appeal, and the Dobs left and I think the new writers didn't know what to do with it. I think that Steve and Carol worked but more as supportive friends...(why does every relationship on soaps have to be romantic/sexual) which would have caused problems enough when her friend Steve hooked up with her enemy Natalie taking her to court over custody, etc.
As it worked out the new writers change whatever the Dobsons were planning with the Egyptian artifacts, to James working with/being blackmailed into a drug cartel. Steve desperate to help his new family and make money, was involved with using his truck to transport the drugs..(as Marland would have him do later) and he was sent to jail for a while, and Carol divorced him and just kind of vanished. During the whole Betsy/Steve thing Carol was never mentioned!
