How do you end the convo over text? I usually end do convo through not responding to the last text or responding after a couple of hours because I don't want to hear they saying" you are such a jerk you didn't respond me back", of course I am not leaving them in seen.

It's just weird for me to say "I gotta sleep now, good night" or "I am preparing sth, I can't type now" for really easy conversations to my plates and just friends. Sometimes they seem they just want to talk to me when I am busy. I feel guilty not responding them back especially my friends, how do you handle it?

Is it always bad for me if I keep ignoring their text not looking into the text and be complete offline so they think I am busy?
