Terrified Of Forever...

My current boyfriend and I dated four years ago. I was 16 and he was 18 in college. He didn't treat me bad but had a lot of growing up to do as did I.

Fast Forward four years I'm now 20 and he's 22. He finished school, I have two children from a very abusive failed engagement of three years. Moved twice to two different states.

I ended up moving back to my home town with my two children and we reconnected. It was honestly like a movie when we met again. We just clicked. Spinning me around in his kitchen a we danced, showers together, late night adventures... He said that my kids are ours. We are now expecting our 3rd child, his first.he's over the moon.

I still have PTSD from my ex... He had a 3rd degree felony plus three separate counts of domestic against him. I keep pushing my newly found prince charming away. Any advice?
