Weird situation with my ex- advice needed!?

[S.]

Ok so I stopped talking to my ex 3 months ago, I blocked him on Twitter, Facebook, and blocked his number. On Wednesday I unblocked him from Twitter, and Facebook only just because I thought it was long enough.

Literally 2 hours later he favorited my tweet I tweeted about how I finally decided to get my nipples pierced (which why would he favorite that when he's got a girlfriend), then he followed me on Twitter.

He's got a girlfriend, has had one for like 2 months, and I messaged him on Twitter asking him why he followed me but I never got a reply so I just unfollowed him.

Is he trying to tell me something?!

Are you trying to tell him something in unblocking him? Why not just keep him blocked? Unless you wanna stay friends with him. He's just following you to stalk you, duh.

no, hes just doing it because he flt like it, thinki about it, if he really loves you, how can he get a girlfriend a month later after you guys break up? he would wait for u wouldnt he? he might jsut want to be friends or whatever, dont think about it, not worth it. move on.
