I do understand what you're saying. However, I do know that I would not want to salvage a marriage if she was unfaithful. I know Dr. Harley has said that he would not salvage his marriage either and his marriage hasn't seen the suffering of infidelity.
I didn't fully recover when the marriage was first recovered the first time, but I was on my way for 5 years. Recovering from something like infidelity is very hard. Some people think that as long as they have allways done all the other things they should do in the marriage, that it should be overlooked when it is a brief indescretion. I stayed because of the children, and the hope that if I kept at it,(like a plan A), she would eventually come around.
To be honest I used to believe that if she screwed up one more time I would be fine if I left. I used to be like that kilt, very confidant and straight foward confrontational about everything.
After all the time invested, and the strength my children felt as they got older by KNOWING emotionnally that Mom and Dad would never leave them, and what would happen to them if I blew the whistle on her. The drama and side taking and even the blame I took sometimes would spin them around. If I just left W would have feel into decline so fast and blame me for it. The Kids would too. Kids are confused by this drama crap. A lot of what I stayed for was for them. I just could not put them though it.
Eventually the motives for the marraige got confused and entrenched as I became more and more sympathethtic to my captor, and it wore me down.
Im not saying that it would happen to you, your marraige is probably more healthy than mine and your wife too. When you have something right going on its easy to spot a dangerous counterfeit. The betrayal is devestating and it is wrong to take it, I don't care what the reasons are and how much you think you can understand and take emotionally. Some actions deserve no mercy, but its up to you to make the decision whether the perpetrator does.
I knew she had issues to begin with, and I thoght I could help her and deal with those things. I thought life had made me that tough. I was that confidant. I was that foolish. It wasn't the infidelity that hurt the most, it was the deception and lack of intimacy honesty brings
I know now there came a point where leaving would have been in the best interest of all, and i stayed because I was entrenched with the problems. Some of the reasons were because She had made such a comeback earlier and that was a hopeful and redeeming time for us all. It is possible that after 10-15 years you might feel different than you feel now. You are here though and have forsight into what happens, so you will not crumble anyways.
