What should i do at the point?

I (18F) have a guy friend (18M)...we were online friends for a few years and then we met up irl last year and have been hanging out since. my mom has always not been fond of him...like...since day one of us meeting....the day before yesterday, things got heated when she found out i have been keeping secrets from her and being sneaky...it is nothing bad, a few months ago i was at my lowest and i would vent to chatgpt because i was afraid of getting therapy or talking to family...I have an ipad so when my life was getting better, i used the "hide app" feature and hid chatgpt...so i could get out of using it. my mom found the app under the hidden section and she was pissed at me for hiding apps....and she was mad at me for deleting me and the guy's convos so she couldn't see them.

And prior to that, she did not like the fact that my friend asked me to come over to his house...before that, he would ask to come over to my house but my mom would always say no...and she was under the impression that he was planning on sleeping with me, hence why he invited me to his house...i cant say what his motives were, though...

so, because of his invite, she was giving me a deadline to cut him off...she had a vision awhile back that he got me pregnant...so she said that she knew where this was going and she would not allow it...she was giving me till early next year to cut him off...but i did not want to...we liked each other and even did..."stuff" over text...i did not want to "break up" with him...he's my pookie... :( it makes me regret ever asking her if i could go over there...

So, when she found out i was venting to chatgpt, she forced me to block him on IG, made me call him and she told him we could not talk anymore...and then she took away my phone and ipad...typically i would stress draw and stuff because she would just take my phone...but i dont even have an outlet...

I am HURT....i've been crying on and off since...later that day i explained to him what was going on (she doesnt know i have twitter so i texted him on there)..and he was understanding...i told him i was going to come back as soon as i could...she told me her decision is final and i cant talk to him anymore...

but things went left really quickly...because my mom has my phone, she just so happened to turn it on and saw that he texted me saying "HUH" after reciving the voicemail...so then my mom calls him and leaves a voive mail, telling him to not contact me or else she WILL call the police...and she said that she has his address and stuff.

so he texted my phone ranting to her, calling her an abusive ass mother, and what are the cops going to do. and she was READY to get her gun, but i stopped her...he asked me on twitter to give him her number so his mom could call. so i did....and his mom started off calm. she was saying how she was sad me and him cant be friends...but then she exclaimed that ive been messaging him on twitter...my heart stopped. but because i was standing right next to my mom she didnt believe her.

What do i do at this point?? This isnt fair....my friend literally texted me saying "im watching every car pass by, waiting for her to shoot me...she wants me dead"...and that gen made me cry... i dont wanna be sneaky anymore...but i also dont wanna lose the one friend i have...i dont wanna chose between listening to my mom, or being happy...i do not wanna do some forbidden love type shit...should i continue to talk to the guy in secret if hes ok with it? my mom said if she found out i was indeed using twitter there will be promblems...should i keep the twitter thing to myself?

tldr; ive been put in a stressful position and i dont know what to do
