Lost puppy is an accurate recollection of what she said. However, this turns out to be partially true of her motivation to seek comfort elsewhere, there was a deeper issue (which could be true or not). When MIL attempted suicide the second time, my wife found her in our home mid attempt (cutting). She ran and hid in the closet and called me. I rushed home and did first aid on MIL (bandaging neck, wrists, and ankles) until the paramedics arrived. She did survive that attempt.
When she wanted to talk about how she felt paralyzed and scared about this, I was a reminder of her inaction. She would visualize me doing the first aid covered in her mother's blood while she did nothing. This didn't give her much comfort. Me being emotionally cool and inarticulate as it came to comforting her over her mother's death was really just a small adder to this mental block in coming to me for support.
For many women, if their husband saved their mother's life - as you clearly did - he would be a hero, not a 'lost puppy'.
It says a lot about your wife's thought processes that your reward for saving the life of a woman she claimed to love was to cheat on you.
The question is, when you are dealing with someone who thinks in such a screwed-up, self-centered way, how are you ever going to get a 'win' out of any given situation?
The problem is that you are playing by two completely different sets of rules. Your wife is comfortable being surrounded by cheaters; you are not.
Your wife feels it is fine to build relationships with other men after having an affair in which she did her utmost to get physical with another woman's husband; you do not think it is fine.
Your wife thought - and may well still think - it is acceptable to pursue another woman's husband for sex when your answer to a poster who asked you when you were going to start branching out and getting involved with other women was, "It will never happen".
You seem to feel bound by a set of personal values, rules, boundaries, and thoughts about marriage that keep you honest, supportive, and faithful to a wife whose value system seems to be, "If it feels good, do it", with no sense of obligation or responsibility to you, and no concern about who gets hurt as long as she has fun.
And if you don't like it, you get told to suck it up by someone who claims to both love and respect you. That suggests that your wife urgently needs to consult a dictionary to look up the definitions of those words, because real love and respect do not manifest themselves in indifference to a respected loved one's pain or discomfort.
A very well-respected poster in these forums called Stevesn always says that if he had a friendship or other relationship with anyone that made his wife unhappy or uncomfortable, he would end that relationship immediately.
That is what love and respect looks like.
In relation to your wife leaving, you said, "If she leaves, she leaves". In relation to divorce, you said that you are waiting for your wife to do something significant enough to justify it, like having a PA like the one she tried to engineer with her 'friend'.
In both scenarios, the prime mover is your wife, with you standing on the side-lines like an an analytical observer holding a check-list. "Well, I haven't caught her doing something bad enough for me to invoke the nuclear option, so I guess I have no choice but to stay and see what she does tomorrow".
Essentially, your wife is governing the tone and quality of your life, because you choose to stay with her, and because divorce is only seen as a reactive response to a bad thing she does, rather than a proactive action taken because of positive things your wife is not doing, like making you feel secure, loved, or respected.
Those things are the standard currency and essential foundation for a healthy marriage, and they are things that you could find with another woman if/when you finally decide that you deserve them, and you acknowledge that time's a wastin', as the saying goes.
If you are just waiting for your wife to cheat again or to leave you, it suggests you accept that you can have a life without your wife.
My question is, why should your liberation only come from a reaction to your wife doing something bad? Why can't it come from something good, like you proactively deciding that you deserve something better in life than your wife is capable of providing?
I hate saying all these things, but I feel frustrated, because you deserve so much better than you are being given.
