<human>: Can you give me the gist of the text in a nutshell?

He is my first official, serious boyfriend and we have been dating for almost a month before making it official. I have never had a boyfriend before him. Because of this, everything is making me paranoid that I can't concentrate on a lot of things. I feel bad when he does not text me throughout the day, I worry if I said something wrong that could've made him like me less, etc. How do I stop being anxious and paranoid? I know he likes me, or else he would not have agreed to make it exclusive and I found out from his friends that our coupling has made him really happy. It's just me who's being nervous about all of this. Help?
<bot>: I am a first time-girlfriend to a boy who has been with a lot of girls, and this is making me paranoid. How to deal?
