How are you and how was your day and whatever...

[Catherine]

We all make mistakes like that. You are in a secure building and you have a dog. Suzy would know if someone was at your door. Also do not open the door unless you are sure who is there. 

I don't block calls, I just don't answer them. That way I do know if someone has called me.  He will lose interest soon enough if he doesn't hear from you.  I think it is always best to avoid an ex. You broke up in the first place. You must have had a good reason. It is unlikely that the person has changed. New contact just brings up unpleasant moments from the past.  Best to leave the past in the past and be careful when you go out for the next little while.  Take Suzy whenever you can.
