What does it mean if my ex unblocked my friends sn's?

some of my friends think since I was upset with him 2 weeks ago and I no longer use aim he unblocked them my friends say it's because of me, I mean he use to block some of my friends because they would annoy him only cause they care about me. I do love him but sometimes he will just ignore me when he gets mad and I don't understand that if you're mad you should talk it out not freeze a person out for weeks somehow I know he'll talk to me again because he always does but I don't want this to happen all the time. what should I do?
