I want your opinion on blocking?

starting off. bfs daughter blocked me on fb, now his son who lives with me has blocked me. (bf is a trucker, only home 2 days a week) how should i handle this? my dad says ignore it. however being the person i am says play along. if i am ignored in FB world which is reality to so many kids, should i not be ignored in the real world? in other words, if he actually talks to me should i act as if i do not hear a thing? what would you do? for insights... he is 17, i have been with his dad for 2 yeaRS now.. have known him for 4.
