YR - Our sitchs seem very similar...I believe I remember you back in 2006 when I came here the first time my H split.
My old screenname was fandgmom back then. H and I reconciled in August 2006. He cut and ran again Sept. 2010. And after all he has done over the years, I am done. I'm not standing anymore. Evidently, he never finished the MLC or whatever it is he is dealing with. Much like you I have done all that I can and I have always, always been true to myself through all of this.
So many tell me that they don't know how I put up with what I did the last 4 years. I guess I just believed his words and ignored his actions. Right or wrong, it's what I did.
Just wanted to say hi and let you know I'm thinking of you and obviously you are not alone. ((HUGS))
