Yes you will push her FURTHER away with your angry outbursts, selfish demands, disrespectful judgements, and other love busters.
If you truly want to save your marriage, you must rise above the victim mindset. Sure you are the injured party here and yes you have every right to be extremely upset with your W for lying and deceiving you about her affair, BUT all your love busting of her will accomplish is that she will get to the point (if she hasn't gotten there already) where she is going to decide that it is better to end the marriage than to live under the present conditions. Is that you want her to do?
All affairs, no matter what type they are, are based on dishonesty. If you want your W(wife) to come clean then YOU will have to create an emotionally safe environment where she is NOT going to be punished for being honest. But I must warn you,
if you want to hear the truth from her, then you must be emotionally prepared for it. If she starts telling you some of what truly happened between her and the OM, then you MUST be
calm, composed and respectful because if you aren't and you start crying, yelling, or displaying any other 'delicate flower' behavior, she's is just not going to continue for fear that you cannot handle the truth.
I reccomend that you read Rippedin2's thread titled
Can't get wife to admit A for he is in a similar situation in which his W doesn't want to tell him the whole truth about her affair, but in his last update he made progress with her because he followed some of the advice given to him.
P.S. READ Dr Willard Harley's books 'Surviving An Affair', 'His Needs Her Needs' and 'Love Busters' as well as Dave Carder's book 'Torn Asunder'(it goes much further into recovery than Harley's book 'S.A.A.').
