What does it mean if a man runs away from home without taking care of anything?

He is really irresponsible. Running away from home and leaving his family regardless of contact shows that he is immature and impulsive. I suggest you ask his friends who know you very well and have a good relationship, or ask his family to find him, or let them send him a message to let him know that his family is worried about him. When he comes back, give him a warm hug, cook him a good meal, or eat out. Let him feel the warmth of home. I really can't reach him, and I can't find him anywhere. I suggest you call the police, although I don't want to think the worst, but to be on the safe side.
