Amy Fisher and Mary Jo

Amy Fisher shows up at Mary Jo's house with a gun which is in a way premeditated. But then it sounds like she didn't go there with the intention of shooting her because then why would she do this whole conversation and faking a name? She just went there with no plan. I think she guess Mary Jo opened the door and she just started busking. The main issue is that she stayed married to Joey for another seven years. Some people when they say the vows they really really mean it or they really really try to mean it. Even if they married Joey. That's such a sad situation.
