Android messages deleting themselves/ Not showing up!
The problem was that the "date" i had sent it on was in the future.
I must have been getting coins in a game or something, so the messages where, according to android, in the future so i could not receive messages from that contact until the 8th.

To fix this problem if you have it either:


Wait for the date to arrive
Delete the messages from the "future" (Not tested)
Set the time on your phone to past the time stamp on the messages


Side note - You can still receive messages in the notifications bar, just not in messages.

You can also send messages, they just don't show up.
