So about three weeks ago me and my ex boyfriend were talking about how he still cared about me. I told him I have a boyfriend. He seems a little upset about it but bot too worriedm However, he never puts in any effort to even hang out. He hang out with this other girl a lot. so now he hasn't spoken to me at all. I won't message him or even add him. Afterall if a dude wants me in his life he will put me there. Me and him been broken up since October. He now unblocks me. My question is why unblock me?
