Been spinning plates for a while.

This one plate I haven't seen for a few weeks. Yesterday I texted her and we quickly established that she's coming over for the night. She works next to mine. She is normally super keen to stay the night.

She comes over and we have a great session.

Afterwards I go shower and get ready for bed on the understanding that we're sleeping in, and I hear that she's fiddling with the main door downstairs. I come down wondering wtf and she just says she wants to leave and her friend is waiting to pick her up.

I say what's up talk to me, she says she just wants to leave. I open the door bewildered (because she couldn't) and she says "just check your bedroom floor" and abruptly leaves, clearly upset.

I go upstairs and she just found another's plate nighty next to the bed I guess and laid it visibly for me.

We never talked of exclusivity or anything like that and I never implied it. One time she probed and I implied that I'm seeing others (she probed around safety and I told her I wrap it with everyone and we left it at that).

Yes it's my fault I didn't hide the nighty, girls are masters of this shit leaving stuff allover your place it was hidden I guess plus I didn't have time to arrange stuff before she came over. My fault.

I'm not going to reach out or anything like that, I may stumble into her again. I plan on ignoring the whole thing.

Wondering if you guys have had this situation before and what happened and how you dealt with it.
