Just searching through some new comedy material on /r/sinkingships and found this:

Link

For those not bothered to read, his girlfriend of 2 years admits to dreaming about having sex with his best friend of 15 years. She sends said friend flirty texts about having sex with him, which the friend actually shows to OP, after he gets concerned about what she has been sending him. She also says that the friends has been coming on to her, saying they would be a better match, and she should get rid of OP.

Eventually, OP's friend shows him the texts she sent him, and says that it was actually HER saying that they would be the better match.

Unsurprisingly, OP has ABSOLUTELY NO IDEA who started (and maintained) these 'flirty' texts/breakup conversation. The girlfriend had admitted to most of the previous stuff but is now fully dedicated to her man after she 'decided it was nothing' and she 'loved him no matter what' (apart from all the stuff about sexting his best friend, obviously.)

EDIT: Here are the top few comments. Take a guess at who they back.
