My ex partner was like this ☹️ My mental health dropped drastically and because I previously suffered with depression 5 years before that I knew I had to just leave I tried speaking to him about his behaviour, trying to plan fun stuff together, he either said he cba or made excuses for his 'addiction' (apparently playing on the pc 12 hours a day while he wasn't working was a way to unravel from his work stress and depression I ended up downloading loads of friend apps and making new friends and that was the only thing keeping me sane when I wasn't working but then I just left because I just felt trapped with him and degraded i didn't get or feel respected, loved and appreciated. Luckily i didn't have children with him because I think i would've felt even more tied down with him and I think his behaviour wouldve gotten worse Maybe try little outings where your family has the kids for a few hours and you go have food and try to restrict phone use? Ortold him you don't feel appreciated enough and overwhelmed?
I’d suggest something similar to Lynds, find some activities to get into. Hobbies, gym, you said reading, do you like the library or book stores? Find peace within yourself first so you’re not relying on him to give it to you. Definitely continue to try to bond and communicate, but trying to force him won’t work. Once you find your own joy and things you like to do, you’d be surprised, absence makes the heart grow fonder, some, SOME, men will realize the absence and the fact you’re enjoying yourself without them and want that time again. Nothing nasty or revengeful though, true enjoyment for yourself. That energy will relay to them. Good luck to you.
Same thing happened with me and honestly withholding sex and giving an ultimatum and schedule to fit his gaming time worked for me also I kinda lost it and kept turning the WiFi off and hiding his computer wires 🤣🤣🤣 hang in there hun if he’s not being receptive to basic communication and meeting you in the middle then he don’t really care. It’s hard forcing someone to care and actually hear you but you deserve that 
My man is the same way except he has a PC. He does the same exact thing of getting amd when I wanna spend time with him and calls me annoying. He always says that he's "joking" and that I need to grow up and learn to take a "joke". He calls me many rude names like fat, wh0r3, b!tch, etc. It's gotten to the point that I just ignore him and when he asks for something I do the same thing to him that he does and I say "I'm getting annoyed with you". He's gonna learn soon that I'm not gonna play these childish games
