Am I crazy????

My boyfriend was married to this girl for 5 years, dated for 4 years prior to that.. they’ve been divorced for 2 years now. They’re still “best friends” and talk to each other about stuff. As if they’re still each other’s ‘go-to’ person.. what is ya’ll’s opinion on that???? Normal? Not normal???? I feel like our relationship is never gonna grow until she’s out of the center of it. And yes. They have two kids. I understand talking because of/about the kids, but they talk every single day. And not even about the kids half the time y’all...
