He disappeared to “work on himself”

Is this crap or a genuinely good reason. I’m super understanding and I’ve had moments where I disappear to clear my mind and focus on goals so I get it. Mental exhaustion, dealing with stress..I understand it all. He just started a business so it makes sense. But I’ve been supportive and told him I’m here if he needed anything at all but I’m still left ghosted. If I text him, he responds and is still nice and all..but I’m not going to be the one starting convos all the time. It makes me feel annoying. At the same time, we aren’t in a relationship exactly..we were talking and starting off as friends to see what happens so I’m not triggered enough to just cut him off. Should I just do my own thing and see what happens? Or does it seem like he’s not worth it?
