<human>: Can you give me the gist of the text in a nutshell?

My boyfriend and I have been together for 7 months now and we typically have good communication. There are some parts of our pasts that we have not disclosed to each other, but have just vaguely mentioned in passing. I want him to feel completely comfortable to tell me anything and everything but I know that might not ever be the case. How can I show him that I support him with all of his possible past baggage and show that I love him regardless of what happened before our relationship? 

Along the same lines, how can I bring that up in conversation about his past issues and try to help him if he is still struggling?
<bot>: Boyfriend hasn't disclosed some past baggage that I know still comes up seemingly often. How can I start the conversation to help him not struggle and show him I support him?
