Did Lori convince Rick to kill Shane?
At the end of episode 9 "Triggerfinger" Lori asks Rick: "You killed the living to protect what's yours?" Upon hearing that Rick did, she clearly then put the idea for Rick to kill Shane because she says Shane thinks that her & the baby are his.

But despite the initial rough patch, Rick was committed to Lori and her unexpected pregnancy up until her devastating death in Season 3 after giving birth to a daughter. Her death left Rick an emotional wreck, knowing his son Carl was now without a mother and he would have to raise the little girl he knew wasn't his.
His obsession with Lori greatly impacted his emotional state and caused him to pit himself against his former friend. Eventually the tension grew too high between the two, and Shane attempted to kill Rick. Before Shane could act, he was shot and killed by Carl Grimes trying to protect his father.
Rick spoke with "Lori" and told her that he still loved her and had promised himself to keep her alive and fix things.

Simple, she was knocked up and had already confessed to sleeping with Shane.

Rick, understandably, took it to mean that she cared more for Shane than she did for him.
When some people experience great feelings of stress and grief, they can begin to see things that aren't there. In some cases, this can be the result of schizophrenia, which Rick may suffer from to some degree.
