Ya know how I stumbled upon your post? I Goooooooogled “I’ve reconnected with an old flame”, hoping to find similar stories. I didn’t happen to find any, right quick (though I’ve read that there are PLENTY[more than half attempts succed, I believe]), but I found your post and figgered, "Well hell to hill, I’ll try 'n MAKE a similar story happen.
Good luck! Let us know…
Was never about being cowardly, and I have never had a fuller life. I am reluctant to impose myself, out of the blue, on someone after so many years without having a very good reason, and over the last few weeks I’ve gradually but irrevocably drifted away from the idea, for that and other reasons.
The key one being that events with someone else have turned for the better, and all in all this new person is probably better for me all around at this point in my life. It is quite likely that the other woman and myself will prove to have grown apart in a lot of uncomfortable ways (I know I have). I’ll always treasure the time I spent with her, the joys we shared when together, but it looks like that chapter of my life is now over. Thanks to all for your input. 
Closed on request of the OP.
