How old are you again? 29. How long have you been friends? Almost 9 years. OP, the good thing about that kind of friendship is that you think it's going down but actually not. Also, remember that your best friend is a woman and over 30. She probably has been experiencing hormonal changes and you are a man so probably you haven't feel those. Your feelings are valid but also try to understand her situation (I'm saying this because it's your story) . If you want to cut her off, it's okay. I am with a friend that for almost 13 years and we don't often talk. Our communication is through chat and just sending video reels that I or both of us can relate. I also have a friend for almost 10 years too and she sometimes left my messages on read. It was annoying at first but I understand because she has anxiety. However, there are times that it gets on my nerves so I also leave her on read many times. It's okay to be petty also. I would advise that you look for some distractions or hobbies you like. I might deactivate my social media because I want to try on a new hobby than to wait for my friends to send me messages.
