I know Lauren and Joey loved each other. Obviously they did but it couldn't have worked. When they had kids the kids would be related on both sides. Grandfathers and great uncles, aunt and cousin at the same time. She probably realised that in the end and that was why she didn't go with him

Had they not let her get away with the drink drive crash, She would have gone to prison and maybe all the drinking may have been adverted

Joey just gave up on her

Why joey and Laura broke up and lwant them back together

Meh, she deserved it.
