I had a brief relationship with a man I work with. We do not work in the same team but the office is large and open plan and we sit relatively close to each other. No one else on the office knew about our relationship, (although I did confide in one person) as it was so new and we wanted to be professional and it ended before it got serious anyway. So no one else is aware of what was between us.
The problem is that the relationship ended badly and the man basically hates me. I am angry about with him about things but I do still have feelings for him. He has since sent me some rude text messages (which are unjustified) and to be honest I feel really uncomfortable working along side him and I feel really uncomfortable being in the office. My productivity has decreased and I am distracted when he is around.
Do I have a right to make a complaint, raise a grievance about the way he is treating me with the rude messages?
Thanks
