Gomis, who joined the club on a free transfer from Lyon last summer, grew frustrated over a lack of playing time during the first half of the season.
Although Bony's exit to Manchester City should open the door for him to become first choice, Gomis indicated he feels let down by the Swans and is considering his options.
"When Bony was here, it was expected that I would also play in a certain number of games, but that was not the case," the France international told Canal Plus.
"I want to play in a certain number of matches
Today I ask myself many questions
I need time to reflect because what was said was not respected
At my age, it is difficult to spend my time sitting on the bench."
Gomis - who has made 19 league appearances for Swansea, 13 of them as a substitute - said he and his representatives planned to hold talks with Swansea before making any decision but the 29-year-old may not easily be persuaded if he feels promises have already been broken
"I have been approached by clubs," he added.
"For the moment I am concentrating on Swansea
Me leaving? It is possible."
