Re: Opinions Needed...
In general, it's considered **unprofessional **to start relationships with coworkers. In the event that things turn sour.........it will not only be very uncomfortable to face that person at work each day......................the other person might find ways to screw you over at work out of spite/revenge.
And as Mamaof3 suggested.........she could just be displaying friendly co-worker behavior that could be misconstrued as a romantic.
