Hey Autumn, you sound like you're doing very well. You will get a lot out of the conference with that attitude.
I want to offer a word of caution for you. There is a workshop that I really like that I've attended over the past 15 years. I hope to take the next step this year. It has been amazing and I have grown so much.
A few years ago, I went to a conference with my W, a business partner and her H. My business partner and her H got a lot out of it and grew individually and as a couple in amazing ways. My W... not so much...
I would submit it is likely ONE trigger that has led to the sitch we find ourselves in, now. I believe it brought up so much repressed issues that she couldn't deal with. She never opened up to me about it, simply indicated that she would talk to me later about it. Never did. And then for a long time would make negative remarks about using the tools as well as the cost of the workshop.
So the point is, keep your expectations low for your H and high for yourself. YOU will get a tremendous amount of value from this, if you are open to accepting it. Your H COULD get a tremendous value from it, if he is open to it. But try not to expect him to. It will be his own experience and let him work through it, how ever much or little it appears to be, to you. Even the smallest amount of growth can be hugely traumatic.
In no way do I blame my sitch on the workshop nor any other trigger. I am fully aware that my W's journey is her own and I only want the best for her and for her to grow, every moment and every opportunity she can, with or without me. It hurt when her path diverged from mine, but so be it. I got through it and my W will, also.
