no its bs. it takes a few seconds to shoot a text. my ex(scorp sun, cancer moon, and all the other crazy) does this crap. she will disappear for a day or two then blow my phone up trying to make up for last two days... saying she was busy when she was really giving her attention to whoever she wants to give it to. that goes for the 12 hour between texts too people.
You aren't a priority. so f em.... but then when they want or need something they park themselves under you and pretend like they aren't selfish a-holes.
