By filing for divorce it will force her to choose once and for all.
Filing for divorce before his ducks are in a row will practically guarantee that he will be relegated by the legal system to being an every-other-weekend dad and distant paycheck.
Betrayed husbands in this day and time, are woefully treated by the judicial system when it comes to their children, their finances, and their property/possessions.
Never, ever issue an ultimatum until you are cognizant and willing to live with the worse possible result.
Being married to a wife who has no problem seeing and having sex with her lover while her husband takes care of his child while she goes out with him is pathetic. No consequences to her actions equals no motivation to change.
Do you also think it pathetic when a betrayed wife parents the children while the wayward husband is out perpetrating his affair? Or actually living with the OW?
Do you have children? Young children?
Would you be willing to refuse to parent your young children because you thought you were making some strategic point in some sort of marital maneuver? Leaving your children to the whim of the woman who just tossed the whole family on its ear? Again, do you suggest that he be willing to prove his point as his WW introduces the children to ~stepdad~ when they all go on a ~family~ date because dad was busy trying to prove the point that he was not a pushover?
A majority of the posters on this forum who have experienced infidelity have "kept" their children while the wayward spouse pursued their affair. Betrayed spouses trying to save their marriage from an affair, have almost to a man/woman worked to keep the family fires burning while their wayward spouse "has no problem
I do not understand, are you are making a distinction between betrayed husbands and betrayed wives?
It's pathetic for a father to care for his own children while the WW does what wayward wives do?
Do you also view it as pathetic when a betrayed wife cares for the children while the WH does what wayward husbands do?
The reality is, that this exact scenario occurs now and has occurred to just about everyone who has personally dealt with infidelity on this forum.
So, your advice to hurtin is to:
File for divorce.
Force her to choose.
Does that about cover it?
Dr. Harley's methods don't have those 2 things at the top of the recommended paths to take, IIRC.
In addition to the methods promoted by MB, I would suggest battening down the finances, examine and make plans for protecting the joint banking accounts as well as the joint credit cards. A WS in an affair (or heading that way) will often clean out the joint checking accounts, choose to not pay for household bills, run up massive credit card debt.
Keep a detailed record of time spent parenting the children. Any details known or discovered about the time the WS spends with the OP, out partying, failing to show up at work, etc.
Keep a detailed account of monies expended for the household, for the secondary domicile, for the children, for the spouse.
Contact an attorney and find out what all of your legal options and liabilities are in the case of divorce and/or continued separation.
Build up a support system for yourself (this is especially true for men, who are often alone when dealing with infidelity) that can help you. Friends, family, fellow religious folks, neighbors. You never know when you might need a ride, or your children babysat for, or a prayer, or a listening ear, or a couple of dollars, or a spy, etc.
Put together a list of choice responses to existing or likely scenarios you encounter with your WS that you haven't handled well at this point or would like to handle better in the future.
Make a plan. Work the plan. Learn to act rather than react. Acting upon your plan will help keep you from being blown about by the WS winds that are bound to be around.
