I'm confused

Being in quarantine, i haven't seen my boyfriend in 2 months. Last week i was in a really bad headspace, so i took my distance from everything. I explained to him that i needed some space, and that it happened sometimes. he said he understood.

But 2 days ago he sent me a text saying that i wasn't a good girlfriend, that i didn't took care of him (whatever that means) and that he was tired of forcing himself to talk to me when he could see that i didn't want to. Then he added that i was in fault and that i should make more efforts for the relationship.

Am i really in fault?
