I know you should never double text

What should i do in this situation.

Plate messages me: "im sad you didnt call me this weekend and ask me out" (i said I would but forgot)

Me: "lets grab a bite next weekend"

Her no response. This was on sunday.

Do i message her again with actual plans, something like "I'll see you sunday" or "meet me here on x day"

Or do i just leave it.
