Why would I be blocked on Facebook?

[Joel]

I'm actually really good friends with one of my exes for the past couple years. We talk and hang out all the time and for some reason when I texted her a month ago she never replied and I haven't text or called her since. I don't get on Facebook that often probably been 3-4 weeks and when I got on today I noticed she blocked me. I didn't do anything wrong at all I honestly don't know where this is all coming from. I'm afraid to call or text her cause I don't want to make her annoyed and pissed off at me but I have no idea why she is doing this and it's really bothering me because we have been friends for so long and I don't want to lose that. We never got into a fight i didn't do anything that would piss her off, I just want to know why. Any advice? And yes I'm 100% sure she blocked me and not her being deactivated.

Move on, it happens. Maybe she has a jealous boy friend who monitors her, who knows and does it really matter? Move on.

Maybe she deleted her account?
