Show me a text message conversation between NAME_1 and her boyfriend NAME_2. NAME_1 found out that NAME_2 is following a girl called NAME_3 on instagram who NAME_1 hates. This has caused problems before. NAME_1 is seething angry. Her messages are short and aggressive. NAME_2 is defensive and dismissive. He refuses to unfollow NAME_3. NAME_1 calls him unbelievable.
