<human>: Using a throwaway. My SO and I have been together 9 years with a 6-month break-up 5 years ago. We've been in couple's counseling the past 6 months to work on our communication skills and see if we're ready to take the next step forward in our relationship. The elephant in the room is do we make each other happy enough to be together as a married couple?

We had our therapy session last week and my SO's answer was no - not only was he not ready, but he doesn't really know himself or  know if I'm the right person for him (sounding a bit harsh but I'm summarizing 75 minutes into one sentence). He thought we were using couple's therapy to figure that out. I was shocked because my impression was that we had decided a few months ago that we were already moving towards that, and at this point we were working through some other issues to prep ourselves for spending our lives together. I know that my boyfriend was working through some issues - depression among them - but didn't know that included questioning me as a partner or our relationship. 

This is not the first time we've had completely different views about our relationship and each other. The session upset me so much that I've been distant and moody since. I've asked for my space and he's respected that, and we've had a few discussions over the past couple of days about whether we should break-up or not, but neither of us can decide either way. I'm torn between ending it for good or trying to work this out, but I'm so emotional I don't know what a "middle ground" could look like between those two. What are good questions for us to talk through tonight that will help us see if we should try and work this out or move on?

Can you condense the text into three sentences or less?
<bot>: 9 year relationship and he doesn't know if I'm the right person for him to marry. We're talking later tonight - what questions can I ask to see whether this relationship is worth working on or not? Any advice welcome.
