Shlok 170

Touching somebody who practices abortion is prohibited due to the adulterous nature of that person which is sinful.  Also association with such a person is inappropriate as the bad qualities of such a person can be passed on to a widow leading to her destruction and ill repute.

Nor should she listen to amorous talks about males.  Such Shringaar Rasa is of two types - (1) Sanyoga and (2) Vipralambha.  The first is speaking of such lustful or amorous things in a crowd of people and the second is listening to such talks.  Thus a widow should refrain from both activities as to act contrary to this again leads to a breakdown in their Brahmcharya Vrata.
