Mom’s New boyfriend…? -This is long, I’m sorry..-?

Okay, it's a long story from the very beginning, so I'm just going to skip straight to... After the second divorce My Mom ended up having. We moved to an apartment, My Mom, My Little sister, and of course, Me. My Mom was and still is a teacher, so, We didn't have a lot of money, but enough to for food, water, shelter, clothing, and sometimes a bit of fun. About a year later, She starts meeting up with guys online, trying out for different guys, and I guess I was a bit worried, but I didn't mind so long as She was happy. She met a guy named Chris last November, and at first, I thought He was cool. I didn't get to meet Him till... About 6 months later. But He was keeping My Mom happy, and that was what was important to Me, based on Her previous divorce. He lived about an hour away, and was I guess middle to high class on the Social level. He had His own house, His daughter, His room-mate, and all these high-tech stuff I guess. And every single day, school day or not, We'd have to drive out there just to see Him. I guess I was okay with that. I barely had time to finish My homework though, and I'm a 3.8-4.0 student, so homework was very important to Me. There were school breaks where We had about a week or two off, and We'd spend it there most of the time. The problems mostly started in Summer when I spent them with My Mom. I guess like a lot of people, I felt ignored. My Mom would spend all of Her time with Chris, and spent less and less time with My Little sister, as well as Me, but I didn't care really. Chris has a daughter named Kaysie, who plays with Asia, My sister, a lot. At first, She got on every one of My nerves, from, crying about pointless things I did like setting up an account on Her Wii system for a game, to things like shutting doors in My face and talking back with everything I did. I talked to My Mom about this, but Chris would always jump into the conversations and tell Me to toughen up and ignore it, and so My Mom would agree. As Summer went on, We spent everyday there. I'm not so much of a huge eater, but like any normal human being, I DID get hungry. But whenever I asked for things, they'd get Me some canned fruit or cereal I didn't even like. My Mom always cooked what She and Chris liked, while I had to cook whatever I knew how to cook, which was only Spaghetti. So that whole summer, all I ate was Spaghetti, Ice cream, Fruits, and Cereal. I'm a picky person I guess.
As time went on, My Mom started actually not paying any attention to what I said. Literally. I once, for some reason I'm still unknown to, had a huge stomach ache and head ache, and I felt cold and sick even though it was burning hot outside. I told Her over and over, but it was like She didn't hear Me. Then She'd talk to Her boyfriend as if I didn't say anything. I was frustrated, of course. And I would always come to Her to tell Her something, like what the kids were arguing about, what I did and felt proud of Myself for doing, but She'd pay no attention to what I said, and again, went to Her boyfriend. I always asked Her if We could go out to eat since there wasn't anything to eat, and We'd just go to like, Cold Stone, the ice cream place, or She'd pick up some fast food, which I'm really against and She knew it. And then other nights, She would go out with Chris to actual Restaurants. That made Me even MORE mad. But I ignored it. They went dirt-bike riding, which I don't like to be on anything with wheels, so, no sense in Me coming. But they made Me anyways, when all I did was sit in the car 90% of the time. Then My Mom and Chris declared that We were moving this summer to a house that was only a few blocks away from MY house. I only knew Chris for 3 months by that time, and I told My Mom I wasn't comfortable about it, but all She said was, Why? Why huh? Why are You uncomfortable? Does He do anything You don't like? No. So why be uncomfortable?
Hellllooooo. I only knew Him for 3 MONTHS. It's not like it was 3 YEARS.
I also had a birthday that Summer, but I was at My Dad's. And for the past 6 years, whether or not I'm at My Dad's or with Her, She would always be at My Birthdays. Instead, She decided to go with Chris to Maryland, from California, to visit His family. THAT just REALLY got Me and ruined My birthday. She decided to go ON the day of My Birthday too. She didn't even CALL until like.. The next two days. So I spent My Birthday locked in My room.
After We moved, I noticed things change. Asia and Chris argued a LOT. Like, everyday, even up till not, they're arguing. They have A.D.H.D. and I'm not sure if that adds in to any of this... But I have homework that I need to do since I'm in High School, and I can never focus. But My Mom ends up ending it. How? By agreeing that Chris was right, and Asia was the "wrong" one in it. My Mom agrees with Chris about everything unless

Hey hun
It sound like your mom is being selfish, she's not meeting you & your sisters needs, which can be difficult to handle. my mom use to be the same way. unfortunately the kids end up suffering and being hurt from this. the best advice I can give you is, trying to pull your mom to the side with just you and her and you sister. and tell her how you feel . if she is around Chris it will just go one ear out of the other. so you wanna make sure that its just you three. tell her that you want to be included in her life and you want her to respect your feelings. if she doesn't listen i would think about living with you dad our a relative until she gets it together good luck hun
