Is it ok to become a monk?

I called All India Bhikkhu Sangha to know whether I can be trained as a monk… ? The person I called said that world has progressed a lot and it is not a wise thing to leave family behind. He said give up laziness and do your household chores. It is a sin to leave helpless family… This has created a doubt in my mind whether I should strive to follow Buddha’s path or should I give up the path and lead a layman’s life ? Is it ok become a monk ?
