How to disconnect family life & become monk? I have a very strong pull towards becoming a full-time monk but being a family person (a son/husband/father) it seems really tough to take-up robe. How do I go about convincing or communicating this thought to my family?

What are the drawbacks if I just leave everything and walk away?
MN82 discusses the drawbacks faced by Raṭṭhapāla when expressing a desire to  go forth:


  Please give me permission to go forth.”
  When he said this, Raṭṭhapāla’s parents said to him,
  “But, dear Raṭṭhapāla, you’re our only child. You’re dear to us and we love you. You’re dainty and raised in comfort.
  You know nothing of suffering.
  When you die we will lose you against our wishes.


Similarly, consider the needs of your spouse and children. Later in MN82 we see the impact on the wives:


  Then Raṭṭhapāla’s former wives each clasped his feet and said,
  “What are they like, lord, the nymphs for whom you lead the spiritual life?”
  “Sisters, I don’t lead the spiritual life for the sake of nymphs.”
  Saying, “Our lord Raṭṭhapāla refers to us as sisters!” they fainted right away.


Going forth affects many. Discuss this with them. Also think about your own motivations. Raṭṭhapāla felt he had no choice in life but to go forth:


  ‘I’ll either die right here or go forth.’
