Shouldn't I talk to guys like that?

I met a guy on an app. He suddenly disappeared while we were chatting and disappeared for almost a year and then reappeared, he told he had problems, he wasn't feeling well. We started talking on Whatsapp and he disappeared for 13 days again. Then I started talking to another guy. He disappeared too and then reappeared. He said he broke up with his girlfriend, he's depressed. Is this nonsense to talk to guys like that?
