Hello new here,
So it only happens when MY boyfriend texts me..
But it'll show up as 2 diffrent conversations but from the same number... Does that make sense? So were having a conversation but some of his texts will start as a new convo even tho its the same one
Is it possible you're utilizing iMessage for iPhone -or- Chat for Android devices?
This could be combining with the SMS messaging creating the perception of what you're experiencing.
Turn OFF iMessaging in your iPhone message app settings , or Chat settings in your Android message app settings.
I would suspect this will stop the experience you're describing.
