Am I wrong for wanting to meet my ex wife’s boyfriend?

My ex and I were high school sweethearts. We married after college and had kids a couple of years later. It didn’t work out and we divorced on good terms. She’s now found someone she has deep feelings for and wants to introduce him to our kids (5 & 7). I told her I thought it was too soon (8 months) and that I’d like to meet him before hand. She got super defensive and told me she didn’t need my permission and that I was being jealous. I’d like to meet him man to man and get to know the man that is going to be around my kids. We don’t have to be best friends or go out for drinks but I’d at least like to see what vibes I get from him. Am I wrong for this?
