Here is my dilemma

I have been with my boyfriend for several years and am already raising my daughters from a previous marriage. I have a 3-year-old son with my boyfriend and, not long after he was born, my bf got a vasectomy without telling me. It really hurt me. He didn’t confide in me at all and I have barely turned 30, which is still young enough to have more kids. He said it’s because he doesn’t want anymore. I don’t know where I see my future going with him. What would you do?
