How do you react to being left on read?

In this case, we've been talking a good amount and then I said something that wasnt completely a dead end, and the person left me on read for about 2 weeks now.

I know they left me on read too bc they've been active elsewhere, so it's not really that they are too busy to respond...but am I being too sensitive here? The person messaged me back but I cba since I really really hate being left on read lmao😬 I also dont want to respond bc I don't like this whole popping in and out of my life kind of thing, but maybe I'm being dramatic 😅
