HELP?

me and my boyfriend have been dating for over a month now and I really like him. I have anxiety and a bunch of social issues, I am always concerned that I am saying or doing something wrong. when I'm with him I feel more comfortable than I normally do around most people and I love it. The thing I'm worried about is that he doesn't text me a lot, and when I try to text him our conversations are pretty short. He is just as awkward as I am so I think it is just because he doesnt know what to say, but I have no idea what I should do. I want him to talk to me more, but I don't want to seem like I'm clingy or desperate. He comes over sometimes and we mess around, we hit eachother with pillows and cuddle on the couch, but over text it's more difficult. the thing is, he is a very busy person so its hard for us to hang out a lot so we pretty much have to talk over text. Any suggestions as to what I should do? I really like him, we are both 15 so it's not a really serious relationship or anything but I want it to last for a while. He is everything I want in life right now, which sounds insane since we are so young but it's true. Thanks to him I know what is important to me in a relationship and I really hope this lasts, I just need a bit of advice on how to keep our conversations going. Thanks so much guys 😘
