How to self soothe in talking phase?

I’m in a talking phase with a girl that I really like. We have a great connection, share the same sarcastic humour/banter, and seem to both be very interested in each other. We’ve been texting everyday now for a week. However, she told me that she has some avoidant tendencies which rang some alarm bells for me as I’m anxiously attached and have been hurt before by emotionally inconsistent people.

Yesterday I hadn’t heard from her for a full day and it sent me into a bit of a spiral. We’re not exclusive or dating yet, so that secure feeling isn’t there for me which made the silence confusing. She doesn’t owe me anything though as we have only been speaking for a week, yet, I felt anxious and uncertain during that day of not hearing from her. I thought maybe she had lost interest or something.

Today, we texted again and she apologised and explained that she was stressed as she had an assignment due that day and said that she was being ‘classic avoidant’. I told her that I can’t (nor want to) change her avoidant tendencies, but that I’ll always appreciate her trying to talk to me and I’ll always listen and care. She thanked me and seemed to understand. I want to see where things lead with her, because I really like her and things are going well. She has been consistent apart from that one day. I just notice that I get invested quite quickly and I struggle with soothing myself when things don’t feel certain. I’ve been feeling really sensitive lately which doesn’t help either. However, this situation could easily lead to me being hurt again due to potentially dating someone who will make me feel anxious. I just don’t know yet how this will play out. Can anyone give me any advice and tips to deal with this situation?
