Dear pipercub:

You are welcome. From what you shared the ex best friend, your co worker and recent short term boyfriend is not well and his relationship with the other woman is not healthy. So it is better for you to not be involved with him as a bf/gf even if he was available. If I was you I would let him know that my relationship with him is now only that of co workers, be pleasant but nothing else.

I hope as co workers, after a time of co workers only pleasantry, things at work will no longer be awkward. Hope you post again.
