<human>: I met "Johnny" 6 months ago through friends. There was an immediate connection between us and we started having sex about a month later. Our individual friends on both sides know about us, but our mutual group isn't aware. We're not at all official, haven't even discussed it, but we go home together almost every weekend. 

He is a really, really kind person. He isn't my type at all but what attracted me straight away was how caring he was. I might have assumed this was just because he wanted to hook up with me, but he's an angel to EVERYONE. All of my friends, male and female, agree he's a really nice guy.

We talk through snapchat. It started when we were still in very early stages I guess because it seemed the most casual way to communicate with someone, but we just never switched to text or Facebook. So weird as that is, we chat a little bit every day through back and forth captions on whatever pictures.

With snapchat, you can see if somebody has opened your message or not. Lately, it takes HOURS for him to open a message from me although he responds straight away once he does. I've got into a bad habit of opening a chat with him on Facebook (not saying anything) to see if he's around, and he's usually active within the last few minutes. 

It's highly possible he has Facebook open on his PC rather than his phone, but what? He just leaves his phone on the other side of the room and completely blanks it?

I have no idea what the reason could be to do that.

Give me the gist of the text in a nutshell
<bot>: Have been sleeping with a guy regularly for months. When I message him, he waits hours before opening them, but then respons totally normally.
