This again!!

Okay for context my boyfriends mom doesnt want him in a long distance relationship and thats what we are. He's had to block me in the past because she made him but he didn't block me on everything so I managed to talk to him and he unblocked me again and we're back together. Well he was showing his mom something and he had his phone on do not disturb and somehow my message went through and she saw it. I am COOKED i cannot go through this stuff AGAIN
