Not sure if this should be posted at the Workplace, but this question (for me) is more about interpersonal skills.
My colleague and I dated for some time, then we stopped doing so later on (she was the one who adduced that we should stop doing so). I respect that decision.
Then after some time, she got promoted (we're on the same team).
Our interaction became awkward and she would often criticise my work standards (I think her criticisms are mainly based on her observation; I never shared with her how I deal with things at work, it just comes to her through shared emails and perhaps the opinion of other people). I am also struggling as to why she criticises me, considering that I received recognition for the work that I've been doing.
I'm not sure if I provided enough context, but that's the summary in general.
We still interact but I know that it's just for the purpose of showing professionalism. I noticed that she tries her best to avoid having an interaction and I try to avoid having interaction as well (considering that she gives her utmost effort). However, whenever I speak up about work-related matters in team meetings, she usually reject my ideas; and I don't understand why (my ideas are relevant to the mission, vision and goals of the company).
Note that our dates were friendly rather than romantic.
I would like to know what are the things that I should do to deal with the situation I am in.
