What does that mean when a married woman asked for lunch?

Anonymous
Hi , I left my previous job like a year ago and I used to have a co-worker. she was married with two kids. we used to talk and maybe little bit joke around at work place but thats was it. she got fired from her job and I also left that job couple months later. recently out of no where , she texted me how am I doin these days and I told her Im planning to move to florida. she asked me then if Im still single or married. I said Im single. and she was like well you can find hot girls in florida and she laughed. then she said before moving to florida can we have lunch together? I know its just a lunch request from ex co-worker but I feel like its odd since she is not my close friend and we haven't talked for more than 18 months.
I appreciate if someone can help me find out what was her intention
