Feeling fearful or hurt that someone doesn’t return our affection in equal measure is the most natural thing in the world. You are in excellent company! Still, we are not entitled to decide unilaterally on “reasonable” response times. (And what would they be, anyway: Five minutes? Five hours? Five days?) Don’t send a text that tries to guilt your relative into speedier replies. She is showing you — through her behavior — the pace of texting that’s comfortable for her.
