A little over a month ago, I was trying to text/iMessage a friend of mine. I put in her name and sent the message, next thing I know, I realize I accidentally sent the message to her husband (who I am also friends with/have in my phone). I thought I wasn't paying attention so I went back and tried again. It's not me. Whenever I put in her name (so it's showing at the top), his text thread appears and all the messages get sent to him. However, if my friend iMessages me first, then I'm not able to text her husband and all messages got to her. Group messages still work but I can't figure this out. If I delete the thread, it seems to keep their messages separate for a bit but then they end up combining again. I've never had this problem with anyone else before and I'm wondering if it's because they share an Apple ID? Wanted to see if anyone has experienced this before and how on earth do I permanently fix it?
