You're talking to a girl you had a very long important and complicated history with.

Your current goal is NOT to be back together at any point, but to keep the sexual side and the connection running strong.

It's been over for years now but after a very long hiatus you've been seeing each other at times for sex and because even if you don't want to go through the feelings route it's obvious there's still some involved and a strong attraction from both parts persists.

She's been in some kind of "situationship" with a guy for about a year, this situationship is based anyway on the rule of being exclusive from your understanding and it has since the beginning.

She starts describing very vaguely to you the kind of "relationship" she has with him and how beautiful the concept is.

At one point she boldly and casually declares she's never wronged him or done anything disrespectful towards him, although a few months ago you two have been explicitly sexting (she expressed guilt after the fact) and every now and then she still lets some sexual hints slip in the convo which goes on almost every day.

Do you bring the incoherence up or play along and why?

Also: I feel like I'm missing some piece of the puzzle here, anyone got any idea?
