Ex got grumpy because I hadn't contacted him in a few days?

We were together for 2 years, broke up one years ago. He's been urging me to call him when ever I need anything, am in any sort of trouble or whatever. So we talked Monday last week. Friday he contacted me to tell me I should have contacted him in the 4 days in between. Wtf is this, he didn't want me in his life so why complain?
