Will my ex feel jealous if I move on with someone else?

Just recently ended a relationship of only 10 months but it was the first time I was involved with someone after the seperation. I have 3 kids and she knew about it and was clear well before we started dating. She seemed fine with it. We had a distance problem and to top it off I would only see her every other weekend which was hard on me. I broke it off but then regretted it and tried to fix it. Apparently she started thinking about things and all of a sudden she said she wants to experience having a baby with someone that doesn’t have one and that she wanted to be the first priority. I mean I cared and even loved her but I don’t think it’s losing her that’s hurting but more so the reasons why. It’s been really bugging me.
