For what it is worth after the fact, I agree withthegirls, in the response to the text. Make him work for it.
Right now it feels like this is the only way he knows how to reach out, in anger and frustration. I used to poke the bears because I didn't like how I was feeling so I might as well make others feel like crap too.
I recognize this behaviour. And what is it you are missing specifically is the perfect response. It would have peeved me, because that wasn't the real point of the text lmao!!
Congrats on S in college. Just got one there myself :))
