I've worked for my current company for 4 years. Our office is a team of 3 we work shifts with 2 staff together at any given time. I get on fine with both colleagues, not friends but we work together well.
Recently 1 colleague has confided some family difficulties, I've listened and advised and tried to be supportive. However this has led to her messaging me at home for advise/to offload. I've tried to keep it brief, not respond instantly.
Last week she was annoyed at a decision I made at work, Although I didn't have to i explained my reasoning and we left it. The fact that she questioned my decision annoyed me slightly as it's not her place to do so and it didn't affect her job.
After work I got a message from her thanking me for being so understanding and such a good friend. I sent something generic saying it was kind of her to say so. I received another long message saying how she wishes she was more like me.
I don't want this, I am happy being colleagues, I don't want the friendship or the drama .
How can I dial this back please?
