I think it's pretty clear that the woman here is treating guys she wants to fuck and those she wants relationships with very differently. I'd also argue that it's definitely preferable to be the guy she wants to fuck here. Are there any serious explanations for her behavior? (I think she's just a shitty person). Some of the comments avoided her behavior entirely and used some exclusivity talk to justify her actions, how do you view those comments?
