Thank you heart and twinmom, I know I really do need to take several steps back, and I am starting to iimplement that now.
went to swimming this morning and ow buff started talking to me and pretended not to know who I was, asking lots of questions about where I lived, about the boys father etc, I answered honestly and without embellishments. When she 'realised' who my h was she acted completely surprised (she wouldn't have won any awards for her performance - terrible! ) she asked if I thought h and would reconcile, I said not that I know of and then she asked if h and ow were serious I replied with I have no idea, not my circus, not my monkey's! I added no extra info, didn't act angry or upset, Yay me!!
upshot, I got to know that ow really is incredibly insecure about her place in h life, now I get to keep holding my head high, work on detaching from h and continue to learn pma and gal for myself.m
