Can someone please help me out here?

Okay soo after my boyfriends baseball practice he looked at a girls butt for about three seconds right? He texted me later on and said “I need to get something off my chest” and then he told me but like too be honest I don't know I got upset and then tried looking at it in a positive way because he told me and soo I thought at least he’s being honest. I don’t know how to react cause like I know it’s just for something tiny but I don't know I guess I’m just like insecure though so that may be a reason I feel like this but I don't know. Help me out girliess🙏
