Question: Why did you unblock him in the first place?
I kind of see his point. Why even create a Journal about it? That does seem a bit excessive and crossing over into Attention Seeking territory. If you have a problem with someone then try and work it out with them privately. If that is not working then block them and move on. Going public (posting a journal) about it will just make the problem worse and make you look bad in the eyes of the general public. It'd encourage your other watchers to be cruel towards them because of something that went on between the two of you. It can also make a bad first impression for you by new visitors to your page.
Do not think you're doing him (or yourself) a favor by continuing to communicate with them. Leave it be.
