My ex is now my colleague at work!!! How can I handle it????

Time to find a new job.

oh brother !!! I cant even imagine, my ex did something like to me and I cant even imagine to have her working at the same company, yes it will be absolutely awkward, but the only person who can help you out is your own self no one can help you brother, you will just have to deal with it, but I get it its absolutely awkward not to mention that is going to pissed you off because its going to be a daily reminder of what she did to you brother, its time to be strong and let her know how is in control. Time to step up stay busy and stay focus in a month you will be ok with the situation. Good luck brother

Don't stress about it for now but if she does get transferred to your department, then just do your best to be as professional as possible. If that does happen then nothing is stopping you from transferring to another department.

This is a tough one. It seems like you're still very angry about the situation. You may need some professional counseling to help you through talk through this and to forgive out how to forgive her*. It's often available for little or no fee through health insurance. Almost everyone needs counseling at some point in their lives.

*The suggestion to forgive her is for you, not for her. When you don't forgive someone it doesn't help you - you are just holding your anger inside.

Hope this helps!

PS May I suggest that the next time you look for a strong woman. A strong person has good character (honesty, integrity, trustworthiness), displays a positive attitude (cheerful, caring, friendly, forgiving, helpful, and respectful), fulfills their responsibilities (for handling pains in a positive way, for always trying to make a good choice, for taking care of themselves, for serving others), gives their best effort, and demonstrates self-control (of their body, anger, mouth and money). A strong woman is less likely to break your heart.
