bled on my exs sheets F22 M24

last week i went over to my exs house. we have been hooking up on and off since we broke up. we had sex a couple times that night and once in the morning. i didn’t realize i started my period until i got to work. 3 days later he texts me and asks if everything is feeling okay because there was quite a bit of blood on his sheets and comforter. and that he just wanted to make sure i was okay. i told him i started my period and i was so sorry. he said it was okay and that he was gonna have to throw away his comforter. i offered to clean it and or buy him a new one. i expressed how mortified i was. he said it’s okay and that he was a bit mortified too but it happens. i feel so embarrassed. does he think im gross? will he ever try to see me again after this? or has this ship sailed completely?
