Why does my ex block and then unblock me?

It means he has gotten a bit over whatever you did to make him hurt, he’s in a vulnerable place right now and while he won’t reach out to you, he is hoping you’ll notice the unblock and reach out to him first in some way. Cause he misses you and most likely still has feelings for you.

Why did my friend block and unblock me?

When did they block you and unblock you? If you were chatting and they suddenly blocked you then unblocked you, it could be because they didn’t like what you said or you made them feel upset or angry. However, if they suddenly unblocked after a long time of no contact, maybe they want to get your attention.

Should I message my ex after she unblocked me?

Don’t message him. He had blocked you and for some time he wanted nothing to do with you. It may never come to be that you and your ex will be casually messaging each other. That he unblocked you probably means that he’s let go completely and moved on.
