Your wife's judgement is so stellar that she chose to have an affair and flip flop back and forth culminating in divorcing you on your birthday and yet HERS is the opinion that you hold onto as gospel truth?
Sheesh. What are you gonna do next, try to sell me some beachfront property in that lovely desert that you call home?
Stop holding on to her ridiculous words (which is called Justifying Her Infidelity) and live your life. If you are truly letting thoughts like that hold you captive then you need to break away from your irrational fears and kick her ghost to the curb for the very last time.
However, if all this is just a justification for why you need to only have monkey encounters, don't bother. Do what you feel like when you feel like it, just make sure that you are operating in honesty and not hiding behind your X's go-for-the-jugular zingers. The fact that you are even dwelling on her comment just tells me how ready you are for a relationship, you just need wise women like me and Jenny to come along and point it out to you.
And dang you for drawing me out, like mojo! I think of you often and pray for you frequently.
