should I leave soon or wait it out?

---please don't leave rude comments--- My SO and I have a beautiful baby boy together he's 15 months old. he has been promising to move us out of his mom's house 5 years now. the years before my son I was working my own job and he would tell me he had everything and I really didn't have to be working...... so years go by still haven't moved...... should I just leave or should I stay for our son....? P.S...I did stop working when I found out I was pregnant with my son January 2016. every time I ask him if we're moving really soon or at least before the holidays or the new year he says it's not the right time or tries to make me feel bad for asking..... what should i do??
