Your romantic inclinations are not a flaw to be corrected; they’re a trait to be accepted. I know you, Watson.
I know you’ll never be happy within the confines of a “traditional relationship” and I said what I said because it pains me to see you try to fit into one simply because it is the default mode of polite society.
– Well, there is no reason to feel pain, because I’m happy with Andrew.
Or would you be happier without him? Alternatively, with him as an occasional sex partner and confidant? Or with him when he’s in the States and free to pursue other interests when he’s not? There are any number of possible arrangements.
All you need to do is find one which is true to your nature.
