I submitted a research paper to a mainstream journal of my math subject domain in December 2023. I did not hear anything from them since, so last month I reached out to them. My editor informed me that she had sent my paper in January 2024 to two referees, none of whom have responded to her invitation till now. She then asked me to suggest "a few names" of some people who I believe could be "good referees" for my paper. She said that she would choose two of them anonymously and invite them to referee my paper but if they too eventually don't respond, then my paper will be rejected.
There are various situations I am thinking about. Most of these have been described in THIS post (suggested to me in the comment below). The simplest thing is to go ahead and suggest her some names from my field. In this regard, my question (which has not been answered in the above post) is this: can I suggest the names of two people who are acknowledged in my paper? Will it be ethical? I am leaning towards suggesting them because those are the only two people I can GUARANTEE will agree to referee my paper.
Another thing I can do is withdraw my paper from the journal without suggesting her referees or waiting anymore. While the journal is not very prestigious, I am sure I will submit some of my other papers to this journal in the future (2-3 years). I am an early career researcher and I have seen a decent number of papers from my math field getting published here in the last 10-15 years. My question (which has not been answered in the above post) is this: By withdrawing my paper now in response to the editor's above message, can I come across as rude or arrogant and potentially sabotage my chances of publishing in this journal in the future?
