I need more time to digest before responding to the advice that has been kindly offered.
In the meantime, I noticed a pinknews article today about Michael Jordan's daughter coming out as gay in a social media post. Something she had previously written is interesting in the context of the discussion here,
I do not understand what she is trying to say about being defined by one gender, but the list of things she wants out of a relationship is a good one. I will need to think more about the extent that I have those in my relationship, and whether they are gone for good or are feasible to restore.“Until love, trust, honesty, respect, loyalty, commitment, genuine happiness and other characteristics or aspects I want in a relationship is defined by one gender then and only then will I discuss my sexual preference.”
