I have a colleague, we'll call her Sarah who is an extrovert. Although she is in a different department I have been working fairly closely with her on a few projects recently. At first I was a bit thrown by how loud and informal she was - lots of jokes and extremely loud laughing - but I got to know her and we worked well together.
Recently, she has become increasingly unprofessional, asking for one-to-one meetings to discuss work then spending them offloading her personal issues on to me. She also comments on people's appearance during team meetings and calls everyone who is female "darling" or other terms of endearment (doesn't appear to do this to the men!!). I know I'm not the only person who is irritated by this but everyone seems to go "oh well that's just Sarah".
What has really pushed this is that as well as the personal discussions dominating at work, she keeps trying to invite me to her house to hold work meetings there (we are hybrid) or asking to socialise outside of work. Of what I can gather she is very lonely, but I have a busy workload as well as a busy social life. When I spend time with her I come away irritated and overwhelmed and feel like I need to lie down in a dark room!.
So AIBU to avoid working with her in future by wrapping up our current project then avoiding any in future? Or should I just tell her/her manager outright? I don't want to hurt her feelings and she seems very sensitive but I can't cope with this any more.
