What’s going on?

So me and my boyfriend are long distance. He usually have to get to work by 7 am, so basically he always gets up before me and I have to be at work by 11 am. I notice lately he would just get up go about his day and I wouldn’t get a message from him until like around 3pm when his shift ends. Then after he get home he will probably sleep and when he wakes up he probably play his game and call it a day. Sometimes I don’t hear from him for hoursssss. So yesterday around 12 AM he texted me and I reply to him like a few seconds, I didn’t hear from him all day until 5pm today. When he reach back out he said he left his phone at home and didn’t take it to work….. mind u he drives and his phone can be charge in his car while he go to work. These type of things of not hearing from him for so long has been going on for days now and when I say something he try to say I’m picking a fight when I’m not. I’m always reaching out and if he don’t hear from me sometimes it’s like he purposely don’t wanna reach out and I’m drained now.
