is my time up ???

After 4 years with my boyfriend  and me being close to 30 I'm slowly starting to feeling a disappointment. 
I love him to pieces and he does to. 
We've been through things that we could have never imagined and still made it through stronger
That's why lately I'm so sure that he is the one and that I am too
He just made the deal of his life business wise and now has enough money to do whatever he wants 
We could start a family right now and be fine 
I also work and contribute to the household 
He knows I want to get married and have kids and says he want that too 
Being financially stable I would think it would be the right time for us to get engaged at least 
Because that's what was holding him back 
And now he won't even mention anything like that 
He will say the best things in the world but nothing specific that we are moving forward. 
I don't want to pressure or start a conversation about this topic 
Help ?
