Most judgmental/least trusting signs/or sign combinations? - Discussions, questions

I´m asking this question as I recently had to end a friendship with a Sag/Scorpio after some time as she didn´t stop her critical attitude. Being part Libran this was somewhat difficult but also necessary and easy in the end knowing that better communication/attitude wasn´t coming. I had liked her direct manner and "unrelenting" idealism and genuinely intense emotional responses but it became too much and directed at everyone and she wouldn´t learn how to just become more easy going. Anyway... although this isn´t the only individual I know with this combination and a similar attitude to other people I would like to know what everyone else thinks.

*or placements that could create a higher level of suspicion or distrust
