I wanted to pull my hair out! (spoilers)

These kind of movies make me want to just pull my hair out. First of all when he was drugged at her house anyone would try and figure that out as to how you can just pass out that much.He wasnt even drinking so he should ask his self why that happened and then all the sudden his ring is missing. I can drink 1/2 bottle of rum and not pass out like that. Then right after she gives herself an insulin shot she is stopped for drunk driving...duh....another strange thing going one...dont they put there heads together as a family??? I would have figured something was wrong with my insulin and had it checked out. Then she is drinking coffee one minute and she passes out. Now come on, the couple should know that anytime something strange had happened the pretty psycho was always doing something with that person. Im sorry but this was really out there and people have to be total idiots to not see this. Oh and I agree with a comment I read on hear that the pretty psycho had a bottomless bottle of sleepy pills. And if my husband had said to me like what he said to his wife when he thought she had been gambling I would have told him to stick it where the sun dont shine and thanks for believing in me and Oh yea where did they lipstick come from on your shirt so see hun it goes 2 ways.
BTW as I am writing this I havent even gotten to the end of the movie yet and I just dont know how much more I can take. The only reason why I am sticking it out is because I am a glutton for punishment and I am not a quitter. But I may be tempted to take my sleeping pills and put myself out of my misery...lol Oh yea my bottle doesnt have a year supply of pills in them like pretty psychos does. She seems perfectly healthy so I wonder who her Dr was prescribing those...must connected to Michael Jacksons Dr.
