Am I in the wrong?(really long) posted in wrong group don’t bash on me 🤦🏼‍♀️

So pretty much about two months ago my mom had company over and my stepdad was doing yard work. He texted me things like this

After a while of being creeped out I texted my mom saying can you come upstairs it’s important. When she finally came upstairs I showed her the messages and she took my phone in disbelief while he read I was feeding my lizard. She came back in the room asking when the messages where (mind you this wasn’t even the first time he talked like this but it made me extra uncomfortable this time). I showed her the times and she was pissed. She shook it off after a while and told me my sister and little cousin to pack a bag and to go to my older sister house for the night. I ended up never going back unless it was to get stuff. Anyways while I was there she was trying to come up with excuses for him and stuff saying it was his daughter from his previous relationship playing pranks and stuff and I went along with it even tho I know for a fact it was actually him. (Why would she have that kind of picture of her dad??) anyways. I reached out to a friend and she said I could stay with her for a while and we could move out eventually and get out own place(she’s 18). After a while of stress free life I met my boyfriend(been almost a month already). I texted her saying I wanted my birth certificate and social security card because I need to get a job anyways (she never wanted me to get one refused to get me an Id and drivers license). It turned into an argument.

They aren’t in a particular order but that went down.

So fast forward to now my boyfriend had an off day and I figured go back down there and get my stuff. She acted like nothing happened around my boyfriend, and was bubbly like the whole argument never happened??. Which kind of shows the pitty party she was trying to conduct there. I got as much stuff I could fill in a bag and went visit my sister and grandma so explain stuff to my grandma. She had no clue anything was even going on because my mom cut contact and was upset with her for the 100th time. (They took my cousin back and she was pissed for no reason, she gets taken care of either home) But as of now my boyfriend is trying to get a good job with his dad 6000 a month and to get a home for me and him and for my friend a joint home basically for all three of us and stuff,(I’ve dated him before it’s not like he’s a stranger lol) I’m also getting a job in the meantime so I can keep busy until then. Am I in the wrong for wanting to move on in my life without her? Like completely remove her from my life ?

****

Thank you everyone for being so nice!

After I get her to emancipate me I will most likely just cut her out of my life completely. I won’t be replying on my boyfriend and friend if that’s what it sounded like! I’ve got an application for a job and I’m applying monday, last thing I need to get from my sisters is my jeans and I’ll be out of that area of town. (Of course still visiting my nephews and grandma and cousin, most likely my sister too) I will probably end up talking to my older sister about taking my younger sister out of that house and stuff.

Also, my “mom” made the excuse of ‘he admitted to it but was physically sick so she forgave him’. She’s always been manipulative towards everyone she’s ever met. I plan to be way different with my future kids so they never have to go through this.
