My bf is a really amazing guy, I have two kids from a previous relationship, the ex was violent so I left him. We're getting on really well as a couple and everything I have ever wanted has materialized in front of my eyes. I know it is time to drop my guard and let him in, but it's hard to let go of the past and it's eating away at me, stressing me out. He sees this as rejection (from my part) but I see it as a defense mechanism that will subdue in time. I want to progress to the next level in our relationship and so does he, but I don't know how to do it? How do we go about talking about it?
