Dempsey again missed selection for defeat at Manchester United on Saturday.
Jol said: "If there is no bid - like Steven Fletcher and Matt Jarvis at Wolves - he could have played until he got his big move. I would have liked that.
"But there is no official bid. It is a very bad situation for us, and for him of course."
The Fulham boss added: "I am not a person who will not forgive a player. I loved him last year but I have not seen him much this year.
"If there is no bid what can I do? I cannot sell him to the non-league or put him on loan at Stevenage. Maybe something will happen next week.
"He really thought he would be on the move four or five weeks ago. His head was turned. He thought it would happen in the next couple of days and it didn't."
