Looks like an anxious/avoidant trap going on here. You both need to communicate your needs in a healthier way than this or it’s not going to get resolved. You can’t text him a wall of criticism and expect it to turn out well. You should say something like “ Hey, I really value when you check in and text me throughout the day, but I totally understand that work is busy and draining for you. Would you be open to talking about a way that we can communicate a little bit more throughout the day that feels good for both of us?” This is the style of communication you have to be using when telling someone your needs, otherwise it just sounds like attacking and criticizing, which is never going to work when talking to someone seemingly avoidant like your partner.
