Can I have relationship counselling on my own?
Yes, and with me it's the only way. If what you want is sessions with both of you in the room, I'm not the right person, and I'll happily point you towards someone who does that well. But don't assume that's what you need. Most of the work in any relationship is done by one person at a time, in the moment before they react. When you change how you respond, the conversation changes, and that's within your reach without anyone else's permission, agreement or attendance.
