Hey Chloe!
I think the best way for you to help yourself not be anxious or nervous around him would to talk to him about how you feel like in person or over the phone. I don't think it would help your awkwardness around each other if you texted how you felt (trust me, it can make situations awkward. I've been there) don't worry about you coming off creepy or weird. Guys don't think like that as much as us girls do. Just be you around him. After all, that's why you are in a relationship right? To find the right person that loves you for who you are.
If you have any more questions, feel free to
