Continued part:
I made a reddit account to just reply to her and asked why she hates these girls so much. She just said “you must be a single mom lol” ans reported me to the mods. I got screenshots and proof it was her. She even made posts about how great I am with her son but she can’t bring herself to like my kids because they remind her of my ex. She calls my girls brats, pigs, and says that she cringes whenever the oldest one uses “baby talk”. My oldest has a severe speech impediment she is in treatment for but her stepmom friends tell her to just walk away and ignore my daughter. She just lied and told me she has a migraine whenever my oldest is over.

She complains about child support even though its no problem, says that she will lay down the law about talking to their mom without her supervision once we are married (not happening anymore), will not let me spend “our money” on the girls without her approval, and they have to be out at 18. Her behavior is not like this and she’s lied to my face about them. She hasn’t worked since she moved in after she was laid off. I guess her reddit account where she blames my kids for her problems is a better use of her time than getting a part time job.

I am mourning the relationship I thought I had and I told her I wanted her out by the second week of October. I was honest about finding her online activities and she had been telling me that she doesn’t mean it and that she just got caught in the community. Of course she didnt have an answer when I told her that I interacted with her. She told me that I’m breaking her son’s heart and reminded me how she supported me through my transition even though I lost friends and family.

I’d rather be a good parent than a partner to this woman. Kate, enjoy your life and don’t date a parent if you hate that they have kids.
