why my blog is now invite only

I have changed my blog to invite only at the moment as my former boyfriend has managed to find my blog and is not happy about what I have written. He is now making treats and demanding money from me which he wont get!

I could have closed down or moved my blog but I decided to make it invite only that way I shall find out who really wants to read my blog other than those few who leave comments. I know I have a lot of lurkers.
