Should I send my boyfriend a birthday text?

I am on one-month break with my boyfriend. I posted some Facebook stories staying at hospital as my dad is being sick. He saw my stories but didn’t bother even to ask. Even some random friends on Facebook would ask about that. Is it a red flag showing that he doesn’t bother at all and showing his character? Or people are supposed to ignore each other during the break? I told him I wouldn’t contact him during this break but tomorrow is his birthday. Should I send him at least a text or just ignore like what he did to me? I am quite mad about this but wouldn’t want to be so heartless. I don’t want to make assumption on his attention.
