I need help w my emotional conflict

i don't understand. so like i was on a call with my boyfriend. and mind you he's my partner for a project, we couldn't see each other today so i couldn't help. but i wanted to help him virtually, but he wouldn't listen. i told him my side that i felt mad that he didn't wanna cooperate and that its also my project. i told him about why i was feeling that way, how i feel like "i don't like being useless hun, can you please cooperate w me" and now he's ignoring me and avoiding me on purpose and he saw my message 2 hours ago, is this my fault?
