did i get groomed? as a 16 year old guy with a 21 year old woman

so i was in a discord vc with a friend helping him optimize his pc and a woman joins and all 3 of us start talking, at first i thought she was pretty cool and i wanted to talk to her more.

the first day we met she'd ask to show both our faces, i was quite shy to show my face so i sent a picture of me when i was 14 cause that's the only picture i felt the most comfortable sending.

she also sent me her face so we both got comfortable enough to show how we look like

when we first started playing roblox she'd make these jokes like pegging in game kissing n allat stupid stuff and mind you this is by the 2nd day we met in conclusion she was making alot of sexual jokes

i found it extremely weird at first since nobody acts like this except if they like somebody ESPECIALLY when one is a minor and the other is an adult.

we added each other on snapchat and i remember she'd beg me to facetime, at first i'd avoid it since i was kinda shy to do it but in the end i did it anyway.

eventually i asked her if she likes me cause of the flirting and she said yes so we became a couple

we were once in call during the night and i got curious so i started asking her questions like what would she masturbate to, what turns her on and she said audio asmr where guys would moan whimper when they masturbate so she asked me to do it and i did,

it was extremely awkward for me i'd laugh in the middle of it but still extremely awkward and uncomfortable but i still did it

so we just continued normally as a couple afterwards still having sexual stuff mainly during the night before she sleeps. and also there was ALOT of drama that would happen because of her overthinking.

one day i got extremely sick and she just came back from a 1 week vacation, we didnt speak basically for a whole week and our first call after she came back she was quite turned on so she asked me to show my dih and start masturbating via facetime, at first i declined since i was extremely sick and the last thing i would do when sick is masturbate but she insisted.

after declining she started getting upset and not responding to me in call (basically being silent)

so she said atleast grab it while wearing pants not masturbate, when i did that she started asking for more like remove atleast my pants then my underwear etc etc...

obviously i didnt wanna continue at first so she started complaining that supposedly i was already up for it but i changed my mind.

so we made a deal that if i showed her my dih she'd give me her number be more transparent with me and show something back.

after she finished she went to bed and i started having panic attacks after realizing what i just did, it made me so stressed out to the fact that i didn't even have my first kiss and i did something sexual to a girl that i fucking struggled to even get her first name because she was so secretive about her personal life.

the next day i texted her and asked her to call and we did, it only lasted 10 minutes and she said she couldn't continue and said she was tearing up via text, i was extremely confused and all of a sudden she said that i should i just forget about her for atleast a couple weeks and i found it ridiculous.

i texted her multiple times and she basically ghosted me and we never spoke again afterwards.

its been exactly 2 weeks since we last spoke.

am really not sure what to think and i'd really love to hear some advice and insight from other people's opinions.
