Welcome BurnedOUt, take it slow-- remember - better to win hearts (your wife's) not arguments--- heard that somewhere..
If she has close friends/relatives in the truth -they will be talking to her about you eventually, so take it slow with her, leave the "bullshit" attitude out, just show her how available you are for the family now, wives love that. You are doing good with the kids as you have stated, have some date night's with the woman in your life, show her the care and concern you gave the "flock".
