I know how you feel on a diiferent level m husband walked out almost 4 years ago after an argument with one of my sons and another had just een dx w/cancer my world fell apart he said he still loved me and cared about me just couldn't love in my house anymore after 3 years marriage and 3 years together before marriage,we were very compatible in every way and had a very deep love . He now has a live in gf for about a year .I haven't been able to move on he said he fell out of love with me a little over a year ago (soon after couple months met the GF)yet all his claims of "we will never be back together again"and me saying I know you are in love with someone else he just says "don't assume anything about my personal life".
My thing could he possibly be still love me or even questioning us getting back together after all this time ...I only ask since he has made o intentional effort to file for a legal seperation or divorce and we just discussed again the upcoming years ins.benefits he gets at work for all of us so another year basically committed to "this"marriage.I know I would not want to be the GF with the wife still in the background so to speak even if she never wanted to get married.

Any advice,comments etc.
