Please help me determine whether or not to include a comma at the end of the third sentence:
"I won't be talking to my ex at the party tonight."
-"But what if she talks to you?"
"I won't be listening to her either."
-or-
"I won't be talking to my ex at the party tonight."
-"But what if she talks to you?"
"I won't be listening to her, either."
Thanks!
