How do you know when you’re starting to love bomb and/or starting to develop a favorite person? (Please be specific about whether you are talking about love bombing or developing a FP)

I’m worried that I am developing an FP again/have not let go of my FP even though we went through a falling out period and I thought I had let go of the FP feelings. And since we have reconnected, I keep thinking I’m still in love with them and I’m worried about love bombing but I’m not totally sure what that looks like?
