My adhd ass forgets to check my texts all the time and was TERRIBLE about this, especially when I get really focused on something. My current girlfriend kept getting frustrated by my slow response time so I started to put more effort to reply in a more timely manner. In summary: rn it’s fine, but if you ask him to start responding more often and he doesn’t, THEN it’s a bigger red flag. Either way, consistently taking more than like 2-3 hours to respond is a little troubling
