hurtpenguin, I've read through your recent posts and there's quite a lot going on here. I hope I can shed some light on a little of this for you. Much of this, of course, is based upon my own experience. The rest is wisdom I've picked up from SI members, the veterans in particular.
PISD) Post-infidelity stress disorder is more or less the same as PTSD, with subtle differences. Take some time and do a little research (even wiki) on PTSD and how it can affect people. Among the symptoms are hypersensitivity and hyper-vigilance. I experienced both of these in those first few months, along with hysterical bonding. It seems that everything and anything my FWW did, or didn't do, said or didn't say, was a potential trigger, like being late, not texting at the right time, being out of the office, or travelling out of town (which is when she cheated). All of this is common, normal and natural. Some people aren't too affected by it. For others, it can be extremely powerful and require professional help. I think recognizing it and understanding it goes a long way to mitigating it and, eventually, letting it go. Talk to your IC about this.
SAHDs) I've done enough research on infidelity to know that there are no substantial conclusions or statistics on why it happens. It's as complex as human nature itself. Being a SAHD has nothing to do with a WS's choices. However controversial it may be in contemporary society, it's not a justification or cause of infidelity. The major factor is simply opportunity. The position in which BHs or a BWs find themselves is the same; they are both financially dependent upon a wayward spouse. That's a shaky situation no matter how you view it.
CoD & CA Tendencies) It seems to me that this is a very, very common dynamic in relationships. One partner has codependent tendencies and the other tends to avoid conflict. When an unstoppable force meets an immovable object, bad things are bound to happen. In our case, my FWW's CoD tendencies were strong enough to lead her down that path of infidelity. I was the one with conflict avoidant tendencies. It's an extremely difficult dynamic to break.
What I've learned about codependency is mostly from my wife, Beattie and others here on SI. What I know about conflict-avoidance is my own life. Now, this is my own impression here, but people who tend to avoid conflict are some of the most difficult people with whom to reconcile. There's a catch-22 element to conflict avoiders. We tend to avoid the conflicts within ourselves more than anyone else. Until your fiancé can stop avoiding herself, nothing will ever truly change.
Exigencies) Life goes on. There will be times when your fiancé's boss calls her into the office for a meeting late in the day. She'll give her boss her full attention, as she should. She may lose track of time. It happens. My FWW's concept of time isn't the same as mine and never will be. She's habitually late. That shit drove me fucking insane after D-day, because I was hypersensitive and hyper-vigilant and hyper-one-step-away-from-go-fuck-yourself.
Again, this is fairly common stuff here. That insecurity is natural, a consequence of the WMD your fiancé just dropped into your lap. But, life goes on and there are still things in our lives that often take priority.
Expectations) A member here often writes that "disappointment is the difference between expectations and experience." Now, I might get this a bit wrong, but another member once wrote that "expectations are premeditated resentment."
Carefully consider what you expect from your wayward fiancé and what you expect from yourself. I know you want to reconcile, preserve your family, and, perhaps, feel comfortable enough to one day marry her. To expect these things to happen, however, will set you up for disappointment. It's hard enough to R and the odds aren't good. Stick around here long enough and that becomes painfully obvious.
The most important advice I can give to a betrayed spouse (fiancé, partner, whatever) is to detach from your wayward and focus on you and your recovery. Forget about R; you don't know yet if your fiancé is willing and or capable. Rid yourself of any expectations regarding the relationship (or what's left of it) and let go of the outcome. You cannot R alone, no matter how much you want it.
Alcoholism) If you think your fiancé is an alcoholic, I would suggest you make AA, and sobriety, a requirement for R.
Stay strong, hurtpenguin, and keep your head up. This shit storm is just starting for you. It gets easier, but it takes time and effort.
