[walking dead] Why was Shane so focused on Laurie?

(Doing a rewatch, I know what happens)

Granted, he had a vested interest in her and Carl (Coraaal). However, after Rick shows up why didn't he go after another girl like Andrea or her sister. It doesn't make sense to me why he'd go so crazy over his friend's wife after Rick comes back into the picture. It's not as if though there was a shortage of women, and Laurie is obviously not going anywhere from Rick, she is thoroughly back with him as soon as he comes to their camp. I guess Shane's character just doesn't make sense to me.

Look at it his way, he was infatuated with her before all of this happened. He wanted what Rick had. Then Rick was "Dead" and he did, sure, shit hit the fan, but he had what he wanted so it wasn't too bad. But then Rick came back, and suddenly that was gone. Then, even more, he saw as Rick usurped everything he was to the group, Lori, and Carl but was doing it *wrong*. He put the work in, he protected them when Rick wasn't around, he deserved them more then him. Granted, this is the thought process of a guy who's world has very literally gone to hell, and Rick just "stole" his reason for surviving. He Became unhinged, probably had some problems before the fall too.

To Shane being with Lori wasn't about getting his Willy wet. It was about fulfilling what he felt he needed and deserved.
