Anna, I really love your thought process and how you have been progressing.
The one thing I would caution you about is questioning whether to continue with therapy. I've felt the same way many times. I've got this. I was a certified hypnotherapist. I know how to handle these things. Until you don't.
Even when things are going well, it is good to just sit and chat with someone who knows you well. I have spent many sessions with my psychologist just discussing press-on nails, polish, and hairstyles. Don't dismiss the value of that. It isn't the typical "therapy session," but it is no less therapeutic.
I started therapy in 2017 and have changed therapists from social workers (LCSW) to a team of PhD psychologists throughout that time. They know me well enough that even when I seem to have things under control, they sense something beneath the surface, and we discuss it. I have never regretted it.
The few times I stopped going (because of cost) caused me to slip a bit. Then starting over with a new therapist meant rehashing old ground. I am still in therapy now, but because I am handling things well, I no longer need to see the therapist every two weeks to a month. Now I see her every few months, and then it is like catching up with a friend.
Another suggestion that I make to couples is to invite your spouse to meet your therapist. Maybe let her sit in on one of your sessions. This lets them get answers to their questions without relying on you. It's a kind of third-party validation. The other benefit is that you get to hear the questions she asks, so you know what is on her mind about the situation. That can help you help her, and vice versa.
Just something to consider.
