I suggest you must leave him as soon as possible.

He must not be in any false sense of notions.Again your decision must be final.

I support the fact a woman might leave a nonperforming husband. It is natural and utilitarian. But you must accept this also.

  1. If your new partner finds a better looking sexy wife or girlfriend, you should allow him to leave you.
  2. If your husband wins a lottery of million dollars tomorrow, your decision must not change.
  3. Your decision must be based on your core values and must not change afterwards.

Whatever you wish from others, you must also grant the same to them.
