Anxious and avoidant in a relationship

Hello! Im a 14y.o (almost 15) female and im new on this app. Im lesbian and im in a "long distant" relationship with my gf or let's say ex gf. Im from romania and shes from Slovakia, shes turning 14 in a week or 2. Im the anxious attachment style and shes avoidant attachment style so if you can help me I have some questions about all this break up im going through since we are lwk the opposite with the anxious and avoidant.

So im very anxious whenever im in a relationship and me and her have been dating for 4 months now. She told me she doesn't really know how to communicate her feelings and things like that but I think I still pushed. For the past 2 days shes been dry so i got scared and kept texting her "are you mad" "talk to me if something happened" "did i do something or something else happened" and things like that and she kept saying its nothing but yesterday shes been more dry so I tried to talk more until vesterday night when she just said "im sorry" and then blocked me everywhere except tg, email and this app Widgetable if u heard of it. I got scared and texted her on widgetable begging her to tell me what's happening and why this is happening but she didnt reply. I dont understand what's happening cause just a few days ago we were perfect. I have 2 suspension that its 1. I may have put too much pressure on her to talk since shes an avoidant so she felt overwhelmed or 2. She always told me she thinks shes a bad gf because I get scared whenever shes dry and she told me she also has mood swings which is why shes SOMETIMES dry but she thinks shes hurting me and she told me before that I deserve better so idk if its because of the pressure I put on her to talk or because of this but I love her and i am willing to wait for her if she will come back. Ive heard people say avoidants always come back and that they leave because they feel overwhelmed but is that true? Do they actually always come back? What should I even do in my situation? Im open for answers especially from avoidant people themselves or from anxious people like me that are/have been with an avoidant!
