It really chaps my [censored body part] when H is slow to respond to texts, but when I step back and detach I realize that when I'm engaging in a healthy relationship with my phone (i.e., not obsessing over a reply from H), I don't respond to texts right away because I don't see them.
Case in point: I sent H a text earlier this morning abt plans for tonight and it bugged me that an hour went by and I didn't see a reply. Eventually I forgot about it and got busy doing other things (such as posting on this website!). I just went to check my phone; he texted back 2 hours ago with a question for me that I've now slacked in responding to. Oops.
