1. Yup!!
2. Usaly just give in or I did say very politely no or gave an excuse tbh really works XD
3. If I had an app where I could copy and paste a response that had a strict but nice/ respectful /angry/ect message and meaning and just send it instead of typing it out and changing my mind halfway ORRR a app where I can just press a button and it deletes all messages/photos from the chat and then sends a message like “I am sorry due to you …blah blah blah … this user can not text you anymore …ect “ and then just blocks them.
