Blocked on Android phone, will my messages ever be read?

Just to keep things short, I was blocked practically everywhere by someone. One day, I accidentally sent a questionable SMS to them. I just hope that there is no chance that they'd ever read it. I've read somewhere that Android pushes the SMS messages into a separate inbox, meaning that the person can view them one day if they access that inbox. That would kind of defeat the purpose of the blocking feature a bit. I just hope they never get read. The phone in question here is a Motorola phone, which I assume has very little bloatware (being close to stock Android). Will my messages ever be read?
