rear ended someone today and the person i hit blocked me?

location: California

i accidentally rear ended someone at a stoplight today after my foot slipped off of the breaks. the impact was made at like 3 mph so it was nothing too major. we both pulled over to exchange numbers, they gave me their insurance info, and we agreed that i would provide mine via text later on in the day (my parents have recently changed our car insurance company and i did not have the info atm). all was civil and they were super nice about it! later we start texting, they send me a video of the damages to their car; relatively minor, about 2 dents which are hardly visible, and even answered some questions i had about the claim process bc this is my first car accident and i was very anxious LMAO.

however, upon sending them a message with my insurance information a few hours later, i realized they had blocked me. i havent told my insurance company anything yet, but should i at this point? not sure what to do and im scared that they’ll claim i hit and ran or refused to give them my insurance info just bc they didn’t receive my message
