Am I selfish to want a divorce?

I want children, but my husband keeps saying that he isn’t ready for one yet. We are 10 years in marriage! 10 years of waiting for him to be “ready”! Before we got married, we talked about this and children was in the books.. he was saying things like “marry me and let’s have beautiful children” or “I can’t wait to have a daughter who will look like you”. I think I am tired of waiting and I want out. Am I selfish for feeling this way?

We got married when I was 24. I am now 34 and he is 40.

We speak about my desire to start TTC almost every time, but he keeps saying that he isn’t ready yet. I have waited 10 years for him to be ready. 10 years of putting aside my desire just to keep waiting.. sadly I don’t know how long I will be waiting for. He gets annoyed when I bring up the topic. Don’t get me wrong, we have a happy marriage… he is a lovely husband but I feel like something is missing and that is children. I am not getting any younger. If I knew that things would be like this, I would not have married him. Sorry if that makes me sound selfish again. Assuming he he had always had this reservation about having kids before we got married, then I could accept that I knew what I was getting into when marrying him but that’s not the case for me. His attitude towards having kids changed after marriage. I don’t know anymore.
