Boyfriend slacking

My boyfriend and i have been dating for almost 6 months. He’s not a big texter, doesn’t really like writing but we call almost everyday so he’s usually very affectionate during calls or when we hang out together. However, I just get sad that our texter are so...bland. Like it’s extremely boring. He leaves me on seen a lot, which pisses me off. Sometimes I’ll be in class and he’ll be home sleeping (doesn’t have a class) and when he won’t text me when he wakes up or the time during. I’ll get home at around 3 and he’s already awake but he’ll text me at 7 or 8. Or he won’t even at all unless I say something like “I’m going to bed goodnight” and then he realises he’s been a dick and forgotten about me. I just get sick of it because I’m continuously trying. Always messaging him, etc. it’s like he doesn’t really care much though text me, I’ll be the ones asking questions like, how was class, what’s going on, etc etc. and he’ll just reply.

I’ve brought it up with him and he improved, started messaging me a little more but then he stopped. I’m just annoyed :/

Edit:

I almost broke up with him a few days ago because I’m sick of pushing him to try because I fell like I’m changing him. I’m asking him for more and what I’m asking for isn’t what he’s used to. Texting might not seem like a big deal but I know he texts his friends and stuff and he’s completely different when he texts me. I don’t kmow, it just sucks. Sometimes I want to talk to him when I’m not home and that means texting
