I gather from what you write that you still love your wife. Probability is that though she could have had a minor problem earlier to you marriage, she appears to have been uniformly good with you till late when due to your either late return from your office or due to suspicion of your possible relationship with either your co working females or outside females as many females are easily available for a price as I gather, could have further aggravated her condition. After all generally women are sincere in love and it could have resulted due to disappointment in love with you, it is your duty as a husbabd who lived with your wife at least for a night or more not to seperate from her but to sacrifice your life for her to look after her health by spending money whatever is necessary. I am sure you love and affection with God's blessings as observed and felt by her will definitely bring her back o you as more than a normal wife with more love to you. Please don't listen to even your parents in this regard though parents are to be much regarded! Your such a sacrice will be fitting to your wife's welfare and your problem thus will be solved soon this way! Best of luck!
