My boys goals canged after his father died

According to my Psychologist I have changed a lot lately. My boy has too.
When he was 6 and until he his father died, he wanted to educate himself as veterinarian. It was  a big change for me to hear, that he changed his wish to be in IT.
I know, where that wish came from. Shortly after his father died, he pronounced, that he wanted to be in IT (just like my ex boyfriend.)
My boy had found a new "father figure", that he wanted to be like.
I wonder, if that will change, now that my boyfriend has left us in that horrible way. But as everything else, only time will show.
