hello friend
our situation is almost identical, my wife said the same to me about her telling me a thousand times when we were together that i was pushing her away, and yes i didnt see it either, only dirrerence is i told my wife i respected her decision to leave and it must of been really hard for her to do, and i knew she didnt wake up one morning and decide to leave, she must of been battling with it for some time, at first i did feel all those things like, why would she just up and leave like that, how can she do this to the family, she is selfish, she is heartless, etc etc. but actually she is none of these things, it took great guts to do what she did, and without it things would of got worse not better, i know how my wife thinks, and by me realising those things and not telling her that i thought she abandoned me and the kids, she now has the upmost respect for me,
i dont know your wife and i dont know her values so dont know if this is something she would like to here from you,
my wife and i are great friends now, there is never any talk of our marriage unless she brings it up first, when we are together i completley detach myself for our situation, but most importantly im myself around her, beacuse if you act like something your not she will see through this,
become her friend again, yes do organise something together, cant say what only you know what your wife enjoys, but make it something different than the stuff you would normally of done, make her laugh, excite her, shes already said your fun, show her how much fun you are. just make sure you detach yourself, remember your starting a friendship,
good luck
