Feeling not worthy

So I was talking to my boyfriend and asking why he doesn’t open up to me with some things. ( we’ve been together 4 1/2 years). I asked him why he ignores me when I ask if he ever wants to get married later on down the road and he said when you’re frontal lobe developes and then said he wants to marry someone with goals and someone who contributes. I do have goals it’s just taking me a little longer then expected and I do contribute I clean and give him money. What more can I do 😔 now I feel like I’m not good enough
