What does it mean when he stopped texting for a week?

There’s a guy I been texting for a week then suddenly says he’s drained and mentally. Is he not interested or bored of me. I wanna know from a guy perspective cause it gets me all confused. I thought things are going well and yet he’s always online or on Snapchat and he was suppose to call last night but doesn’t.
