Well written, almmost thoughtful and free of the idiocyncracies many authors fall back on. You could have developed the pattern of behavior that Kit has fallen into - taking married men as lovers - more thoroughly. Certainly in the "real" world such behaviors exist, but usually the person is not sufficiently self-aware to know that she has fallen into one. You might want to consider this as the basis of a new story. It could turn out to be a tremendous, thrilling story in which the heroine tears herself away from her lover, her true lover, and faces the uncertainty of a future without a companion.
One flaw which I think you could easily correct is the use of comma splices and the run-on sentence. In general, do not use commas! They should be used only when your reader will become confused if you do not use one. Here is a comma splice. "She was radiant, he loved her completely." These are two separate sentences. The first should be ended with a period or the comma should be replaced with a conjunction, and, in this case. Commas can be used to indicate a slowdown of the thought process. "Well, he thought, I could buy flowers." They can be used to separate a name in a sentence of direct address. "Kit, will you please stop making that noise?"
The more you write, the better your writing will become, so please keep writing!
