<human>: Give me a shortened version of the text

I'm all about communication in a relationship and he knows that. Every weekend it seems that he disappears for hours and ignores my texts. I always had a feeling he was ignoring me, but every time I mention it he says he just didn't check his phone... for 4-10 hours. 

Last night he went to a BBQ and I asked to meet up later, he wanted to, so I left him alone for a while. I text him around 10 to see what he's up to and don't hear back from him until about 2 am. At this point I'm in bed scrolling through Instagram and notice he's liking other people's photos but hasn't responded to the other handful of text I've sent him asking if he's alive/home. 

This may not seem like a huge deal, and in the grand scheme of things it isn't, but we've had multiple conversations about him forgetting we made plans, or not checking in for several hours. I'd like to know if we're not going to hang out, so I don't waste my night waiting around. 

So at 2am he texts me saying "I'm alive, I am sleeping. I had a long day. Let's talk tomorrow, can't have this conversation tonight." At this point he's still liking photos on Insta and ignoring my calls. I guess what I'm trying to say is I feel like I'm not being heard or valued in this relationship. When we're together everything is amazing and I feel like the luckiest person ever, but at lease once on the weekend he'll disappear at night and I'm forgotten about. Is there a good way to resolve this small communication issue? How can I approach him without being too confrontational. I feel as though we just don't see eye-to-eye on this topic and it might be less stressful to just go our separate ways and look for people who fit our needs. Thoughts?
<bot>: Boyfriend disappears from text for hours and hours at a time then doesn't have the courtesy to talk to me about it because he's tired.
