Before i start the reason im writing this is because whenever i have approached my dad about how this woman who is age 50 is becoming a total monster he just says that i don't know shit about the world and even tell me to get a life. But my dad is suppose to be the same smart Alpha man i knew years ago. He is only 52 or so but he has devolved into someone who has become worse at his bussiness and just sits around and watches T.V. Btw my Dad has been called very good looking his whole life and I myself am also good looking and educated so this isnt the complaint of some hill billy trash family problems. I really need you guys to give me advice here.

My dad started dating this woman about 4 years ago. She was really nice and sweet. She made good money as a lawyer and use to buy me stuff all the time. I would stay over at her condo for a week at a time. When her and my dad had split up i use to give her advice and help get them back together. I use to call out my dad on how he wasnt being Alpha enough and how he had to treat her better. She use to take my advice and take me seriously as a person. It was the best of days. Then over time she started asking tons of questions. She always wanted to know everything about everyone. She stopped listening to me completely and stopped trying to improve herself at all. She started putting on a bit of weight. She started blabbering about every single daily activity and things she was doing with her friends and work non stop. Totally uninteresting shit. Her daughter is a girl who got pregnant at 18 with some loser but now goes to a university and has her degree in psychology. Even though the both of them are suppose to be considered professionals in the work field they are both irrational, and argumentative just for the sake of arguing.

Back on topic. My soon to be step mother slowly over time stopped doing jack shit for me. She got a dog that is cute but the dog is constantly breaking all of her stuff. (The dog never gets a hold of mine and my dads stuff, it seems women for some reason have a hard time taking care of animals and keeping their stuff from them for some reason). Literally all she has to do is push in her chair and put her stuff on the table to keep the dog from getting it. Instead she bitches for an hour a day about how the dog keeps getting her stuff. It makes literally 0 sense. She is constantly leaving things like her hair iron plugged in and turned on. I have to walk behind her and turn offf the lights to the bathroom/unplug all of her shit because the last 2 years or so she refuses to clean up after herself. She makes excuses for every single one of her mess ups and refuses to acknowledge her flaws at all.

Even though she is a lawyer, she is a shitty one. She makes good money but only because there are a lot of desperate people who will higher the cheapest lawyer they can find. Her new favorite thing to do the last year and a half or so is pick fights with me trying to disprove all of her flaws by saying things to me like "well your sitting around the house all day you can clean up after the dog" (im a college student who writes articles online). She will say that in response to me saying "Barby, why don't you just push in your chair so the dog doesnt climb on the table to get your stuff". The woman has become insufferable. She never shuts the hell up, she puts herself in everyones bussiness, and if you are every having a conversation and mention you like anything she will automatically say "Oh yea i really like that to!" and then jump into a 1 hour monologue about how her cousin use to do that specific thing that I said I liked. It has become hard to even have a conversation with her.

I recently had to teach her about how dinosaurs didnt live on earth at the same time as humans and how they lived millions of years ago. How is a woman a lawyer and doesnt know jack shit about anything?

TLDR:My soon to be stepmom use to be really nice, lately the last year and a half or so after 3 years of dating my dad she started turning into this monster asking questions constantly, never shutting the fuck up, picking fights to cover up her insecurities, and being completely irrational. She stopped listening to my advice after i had helped her out so much during difficult periods in her life. She is escalating in terms on being a nuisance and no matter what i tell my dad he just tells me that i don't understand how the world works. I know im right here i just need advice from you guys. Today i exploded and ran at her and grabbed her arms and told her to realize how much a annoyance she has become after she told me some dumb shit that i dont remember anymore. She just told me something a insecure 14 year old would say in defense and then cursed at me. So im desperate coming to you guys for help. I fell like my fathers dignity is lowering because of this woman and I don't know what to do.
