Can Therapy "Fix" Homosexuality? - See What It Did To Highsmith

I have been off and on a bio of Highsmith: Beautiful Shadow - A Life Of Patricia Highsmith, by Andrew Wilson, in which there is an anecdote of Highsmith that I could not get over it:

During her late 20s, Highsmith was troubled by her sexuality and she sincerely wanted to fix it, because she wanted to marry a man who deeply loved her. So she underwent a therapy, believed it would eventually convert her to heterosexual. Since the therapy was extremely expensive, she had to take another job in a toy store to catch up with bills. It was in that store she met a female customer, who inspired her to write her second novel Price Of Salt (also published as Carol in later editions) - one of (or the only one) greatest romance books about lesbians relationship, or any love relationship!

After being so thrilled by the ending of Price of Salt, I could not help to go back reading it again, mainly the beginning, where I thought it was slow and boring. Oh it must be I who was slow and bored, because this time I found it enchanting and necessary, so necessary that only after we read all those passages could we be prepared properly for the arrival of Carol - "an amalgamation of all qualities Highsmith admired in a woman" (Beautiful Shadow - A Life Of Patricia Highsmith, Andrew Wilson).
