Found a good Christian man but I’m scared

Hi everyone. I was diagnosed with PTSD a few weeks ago, before that I just thought I had depression and anxiety but I was diagnosed with PTSD. My therapist suggested I take a break from dating while I heal.

However before we had that conversation I had met a Christian guy on a Christian dating app. He is a 7th day Adventist, which I am not, I’m nondenominational Christian but honestly that doesn’t matter to me. He is extremely kind, close with his family, doesn’t drink, smoke, has goals for marriage! We went out and we had fun and he said he can see himself being in a relationship with me! He is pretty much the perfect guy. My only thing is I’m very scared to be heartbroken again! How do I know if this is something I should pursue or not?
