heathy relationship

I am pretty sure tht I have no idea of how to have a healthy relationship, I never have had one I want to have one and I just started this new one. he is a really great guy, but sometimes I feel lost, I am so insecure and I don't want to be...which leads me to do stupid stuff. I texted mike which what I thought was his break and he didnt answer me. so naturally it wasn't anything important be I was afraid tht I had freaked him out and he didnt want to talk to me... we are techly dating but we tlk everyday thx to text.... I am afraid tht I am going to scare him away!
