Should I unblock him?

I blocked him on fb and whatsapp fb I will keep him blocked, but whatsapp I am not sure what to do? We broke up last month cause he was being distant and ignoring my calls and never had time to see me...then he added girls on fb so I blocked him and I bump into him with a girl but he said it was a colleague...i don't know what to believe as he has been acting shady!

I have done it in the past blocked then unblocked etc...but this time a friend said block and leave it I have!

He message me the moment I blocked him asking why I keep doing that but I ignored it, and now I have not heard anything back since from him...he has not made any calls or text so why is he bothered about whatsapp?

Now I am not sure what to do, do I keep him blocked or unblockhim?

someone please tell me!
