Kim, I am pretty much like you, I don't think that i will find another partner again, and will stay alone for the rest of my life.
Being lesbian does not make it easier, to find somebody who wants to share her life with me. I missed the boat for a new relationship after my wife and I separated 16 years ago, but for the longest time after that I was not ready for a new relation, because I still loved my wife and did not want to betray this love.
I am told that I was a good looking guy, and I could have had other women, but I did not want to. Shortly thereafter I started my transition, and now that I feel very much that I arrived, I am to old to attract many other people.
But I am a woman now, and I am happy about it. I am very secure in my femininity, and any further bottom surgery is of cosmetic nature to me only.
The price I may have to pay for this happiness, is being alone, but over the years I got used to being alone. Most cis women of my age are alone, because they lost their husbands. I am just one of them!
Would I have done anything different, yes, if I would have had control over it, but I did not make the decision for transition, I occupied only the body it happened to.
