18 and strict mom part 2

my boyfriend and i had split after a year. but he had asked me to meet up so we met up at the mall (which i never told my mom about) it went pretty well and we had been texting each other. i even had him over to my dads house (my parents are divorced) to let us have sex. i have never told my parents that i’ve let him come right after school to have sex (and i know that’s wrong on my part) but while my ex were together my mom would make his aunt text that she would be there or another adult. it even got to the point where she would barely let me go to his house. she had put me on a tracker when i was like 16. but she read all the messages from the past few months from my ex boyfriend and i, which did not go well since i mention things about how my mom or my brother are, us meeting up, sending flirty messages. she screamed at me and doesn’t want me to talk to my ex anymore. and yesterday i went to his graduation party after going to a friends and she caught me there. i didn’t plan to tell her once i got home cause i was talking to my ex grandma and family. this is the message i got this morning and how she typically throws stuff in my face. idk what to do anymore. i know i have lied but i feel like i am treated like a child.
