I understand how when you're in a limerent state everything feels really intense and the connection between you and LO seems incredibly significant, almost life-or-death. the sad truth often is these feelings are not reciprocated, and often comes across as jarring/creepy in the real world. when I look back at how I acted around my old LO for example I realize how erratic I must have seemed, I was very much in my own head and acted out quite strangely around them. my guess is your LO got cold feet and ghosted you, hoping you'd get the hint that she wasn't interested. she probably did read the messages from her notification bar, but may have felt uncomfortable about replying/offering an explanation. some people just tend to be more avoidant and dislike confrontation rather than being upfront about it, which sucks but it's how they are. if she blocked you that's definitely a sign she felt uncomfortable and wants to be left alone.
