I blocked someone by mistake, while texting....cant find how to unblock it on my Classic BB

I was multi tasting, and you know how it goes.
I was receving a phone call, a mail and texting a friend and it happened all at the same exact second.
I was replying to a text when a call and a mail came into my phone.
I think when I started to type back to the text, somewhow my phone blocked her, maybe the keys I was using unleash some code?
I cannot send or receive texts using the text application.....however, if I go to my contacts and look up the name, I can read the texts she sends me and I can also text her.
I looked on settings and tried different things to unlock it, but still a problem.
This issues is just with my friend, to everybody else I can text normally.
I even tried to delete her contact info and re-enter it....still blocked.
Thanks!

There should be a section in your settings to show you blocked numbers, and you should be able to delete it so it works again.

There is really no way to block numbers natively in BB10. You can set up parental controls so you can only receive calls from someone in your contact list. I suspect you may have a 3rd party application installed that is handling call blocking.

Hello. I blocked someone by mistake today. Were you able to fix it? I tried everything except resetting my BlackBerry Classic to factory settings.
