From what I know about him, he seems to be really busy with his job. He only ever texts me in the morning but mainly does so at night around 9 or 10 pm onwards. Sometimes my messages are 'read' but I get no reply for over a day.
Is this a sign that he's not that into me?
I'm a big texter and my previous boyfriends would text me throughout the day so this is sort of new to me.
