16 year old boy here. A few weeks ago this girl made it clear that she’s interested in me and gave me her number. She’s pretty cute and is fun to be around so I could really see myself growing to like her a lot. But one huge problem I have is that I never know how to start good convos. I always overthink what I’m going to say and become too anxious to even attempt to start one so I almost never end up talking to her, but she still makes it clear that she has interest in me. I’m really worried that I’ll brood over what to say for too long and she’ll end up losing interest in me. How can I overcome this?
