A photo of lesbian drag king Stormé DeLarverie from 1961, you may recognize the name from Stonewall

left: "two friends at the park" (1965)

right: "two friends* at home" (1965)

*the one on the right has "two lesbians at home" written on the back despite being displayed as "two friends," so you can probably guess about the first one off of that

From what I've been reading, it seems they mutually felt that their separation was necessary for both of their careers to be what they were. Allan moved to pursue acting (and so we get him as Freedman!) and in one interview said in retrospect thought she wouldn't have expanded so much artistically if they'd stayed together. Everything I've seen gives the impression they were still close friends afterwards.
