Hi Sue, Thanks for dropping by my thread. I have read what you posted here and it brought back many memories of my "dark times" so I truly feel for what you are going thru. I agree with Rachael tho, there is much hope here. That fact that UR H has included you in his friendship with this coworkder seems to be his way of reassuring you that there is nothing more to that relationship then friendship as far as he is concerned. So the best thing here is try to let it go. Hard to do...VERY...but it is what you need to do in order to allow him to decide to come back to U in the soonest timeframe.
Right now you need to give him space to sort out his issues. Work on what you need to do to make you feel better about yourself and would make you more attractive to him. You will need to demostrate these change are for real and that you will not go back to the you he thinks you are. This takes a lot of time and effort, and is paced at his timeline to figure all this out so it requires lots of patience too, but in the end it is all worth it.
