Hmm what to do everyone are reaping their karma , your chart indicates problems in married life not happy marriage, always in the mindset of parting away . currently you are undergoing unfavorable period which gives you problem nor only in married life but also every side , even professional life is nor that much good .
lord of spouse 7th n family wealth mars in 6th aspected by saturn indicates problems in married life and finance that too saturn dasa in operation though yogakaraga for your chart he is afflicted , associated with sun and ketu and aspected by rahu . you are the reason for her going away . your harsh dealings made her to take this action . you have inimical attitude towards her . no women tolerate that . saturn dasa last till 2031 . and saturn is in mars constellation. for me its seems divorce call . if you manage to move this saturn dasa esp mars rahu sub periods you have chances to patch up else it leads to another marriage .
reg children even though she may take away now but bonding between you and your children never break . daughter likes you and even after legal separation she will have touch with you , but temporary physical separation from children indicated . in d7 chart also 5th lord is retro with mars who is 1st n 6th and again saturn aspecting 5th . so throughout this saturn period this story continues . next mercury dasa is nice overall . between that you get good things on and off . finance will be manageable , mom health affected , changes in residence , enmity with siblings or their with troubles . esp sisters .
unless you change your attitude problems wont solve ..
