Abigail has an affair with John Proctor which leads to her being kicked out of the Proctor household. She has sex with John Proctor in his barn where the animals live, so it is reasonable to suggest that she likes him "more than a friend". Later, Proctor will say that the barn was the "proper place" for their encounter. Abigail never lets go of Proctor - she tries to be with him until the bitter end - but Proctor reall does regret the affair, probably for all the trouble it causes his wife Elizabeth. Abigail's lust for Proctor is at the center of these witch trials - it is a lust that condemns everyone to suspicion.
