<human>: Provide a brief overview of the text.

My friend, "Jane" and I have had a really snarky ongoing banter for the duration of our friendship. Up 'til recently, it had all been in good fun, but a couple of days ago, a mutual friend, "Mike" said I'd offended Jane several days prior. I'd seen Jane since the alleged incident and she didn't mention anything. 

I have no reason to think Mike is making this up, but I'm confused as to why Jane didn't say anything to me. I'd asked a few times in the past of something I said was over the top, and always tried to leave some sort of line of communication open. Further, she knows I suck at reading social clues and have to be told things fairly bluntly (we've had conversations about this - I'm not just guessing that she knows).

I'm sad that I've hurt my friend, but I'm also hurt that I found out from a third party. It's also making me insecure about what she actually thinks of me - if she took a comment I made seriously, then perhaps some of the seemingly playful insults coming from her were genuine?

Is there a way to salvage this friendship? I have no idea how to bring up the topic with her, since she's always said things were fine. Is it appropriate to bring up how the situation makes me feel, or is that selfish/wrongheaded of me?
<bot>: Found out from "Mike" that I offended "Jane," but Jane hasn't said anything. Sad, hurt, confused, and unsure of how to proceed.
