<human>: Basically, I wasn't texting him much while he was at work, even though I know he has a break every 2 hours and when we would be texting & he wouldn't respond, I would just let it go & have him respond when he could. He told me this made him feel like I didn't love him & that I didn't care. 

Over the passed week or so, I changed the behavior. I started texting him around when his break should have been & sending a second text 10 minutes after the first if he didn't respond. Things seemed ok, until the conversation in the snapshots. 

I just don't understand what I am doing wrong.

Can you condense the text into a few key points?
<bot>: My texting choices were upsetting my SO, I changed them, he is still upset, I don't know what to do.
