What does fighting or resisting look like to you? If you mean contesting the Divorce, don't do it. It will cost you thousands in legal fees and you will still lose. Once she tells a judge that your previous porn addiction makes living with you untenable, he will grant the Divorce. You've caused aggro and it'll strengthen her belief that she's right.
Most of us here think that your marital problems were not insurmountable and that she may be overreacting BUT that is her right. It may seem unfair and she may have been influenced by others, but that is her choice to say enough is enough.
I know we chewed your ear off for being weak and helping her with the house etc. There is a vast world of difference between helping her divorce you and being obstructive and resisting. You can be pleasant and amicable without helping her out with this.
I cannot see that you have much choice here. You are not in a position to take aversive action and force anything. IF you get the opportunity then you can say that you think the M is worth saving. Otherwise you have to stand strong, be pleasant but not a push over and wait for an opportunity. It may never come, but then again it might.
