I've noticed myself being even more attractive to other women.
I am assuming you meant that word to be "attracted" and not attractive.
Hope...Right now you have a WW who has gone out of her way to meet 0% of your EN's while you attempted to meet hers. That one way street is killing your L and your marriage like a cancer. It is killing it slowly..and it is almost dead for you. You have accepted that no matter how sucessful Plan B is you may never have your W back. You're ready....for what? Plan B with all the necessary steps for Plan D.
Like in my case I believe that your W will sooner or later "come around" and it may be too late...I especially feel this will, just as in my case. be when you're finally feeling "happy"...with yourself, enough to let someone in your life....
What you're doing now regarding the EN for attractiveness is not an EA unless you're having an emotional attatchment to this person...an infactuation of such with hopes for more...which I have, on numerous occasions warned you against...because you are married...even with planned separation....you're still a married man...
Everyone here tells us two years...wait two years...I did not...heck...my marriage was dead for 3 years prior to D...and I waited a year before dating someone seriously...and within 4-5 months of that I was reconciling with then XW!! Was 2 year window proper? Many would say yes...I still do not know...
at this time I still warn you to proceed cautiously, even if Plan D went into effect tomorrow...you sir are rightfully an absolute emotional mess...do not, under any circumstances bring someone into your life that you think you care about or you think you may care about...cause it will NEVER work..
There..it's out there my friend, as always I wish you the best..
