Sounds silly, I know.
I work with her sometimes, she is casual staff where I am permanently employed. Somehow she picked up more shifts post break-up then she ever did before, or at least it feels that way.
We stick to small talk, usually she is quick to spill her beans about her little life and all I have to do is listen and acknowledge. Tonight she asked me some questions, this doesn't usually happen. She asked me how I was doing, what was new. I can handle these. But then she asked me about the cat, "How's your cat?". It felt like she was the Kool-Aid pitcher crashing through my own wall.
I am ok, but I feel like this was too close for comfort. She told me it had been a long time since we had talked and that she would like it if we could get together sometime. It's likely that she is single, or struggling with her relationship. I feel like she is taking me for an idiot, a large part of me wants to be nice to her as I somewhat understand she is not well. I have grown so use to the small talk that maybe I had manage to depersonalize most of it and saw it as robotic. Maybe that question about the cat made it more human. I don't know.
I would like to be able to have a normal conversation with her again without feeling this way. I do care about her, I never really stopped. However I made great efforts to not involve myself in her stories and I would not want to be involved in hers.
It's strange because if it was anyone else I would have absolutely zero qualms with letting them know I am not ok with discussing personal matters.
I think that no one can really tell you how to handle this since you work with her, but this is what I see:
You still have feelings for her. You are aware of this and keeping things in check.
You're trying to figure out what your boundaries are - and for some reason, the question about the cat crossed a boundary for you. Maybe because the cat was a very real reminder of the life you shared together, but I'm not sure.
If I were you, I would spend some time figuring out
why that conversation was a trigger for you. I think that if you figure out (very clearly) what your boundaries are, that will give you clarity - and peace - even when you have to interact with her.
