“There is nothing she can do.”
Johnny, see the suttas for lay people as Dighajanu (Vyagghapajja) Sutta. Me I couldn’t find any interdiction on relationships for lay people.
Lay people can “live their life ” as much as they avoid debauchery, as much as honesty chairs the relationship process.
Moreover, the suffering will be proportional to the individual’s degree of greed and propensity to attachment.
Obviously all the above applies only to lay people that “don’t intend” to attain the highest Nibanna.
