Divorce, marriage, baby talk.. advice?

Hi there. A little background, I’m in the final stages of divorce (it’s been a long time coming) and my current boyfriend is pushing so hard for us to get married when it’s final. We were together for 2 years roughly 8 years ago and We’ve been together for a year currently. I don’t know how to tell him I’m not ready to jump into marriage again.

He’s also talked a lot about wanting a baby with me, we were expecting 8 years ago but I miscarried. He has an 11 year old son from another marriage, and I am so fine with keeping it that way for a while.

I love this man and his son with all my heart, I’m just scared and feel like things are moving too fast. Any advice?
