I told him that I am typical person who response fast in texting. And if he cannot reply me for the moment, he could text me a text said hi, I'll answer it later. I also told him to be more open to me, and he said he will. Normally he will do it after I told him, but then he will back to his habit. I don't want to tell him the same things many times as it might be annoying. And I have questions, if you had been with your GF/BF awhole night until the next morning and you separated to work the entire day, will you text your GF/BF later in the night or after finish working? Or you will text the next day as you have spent time mostly with her/him? My BF also said to me that there will be sometimes he need space alone. But he won't reject for texting.
