TLDR: Gf mentioned we should do couples therapy. We hadn't really been dating super long and I thought it was kind of ridiculous to go to couples therapy after not having been together more than a year. Changes are happening "too late" according to her.

I recently made us a couples therapy appointment as well as finally getting myself some appointments set up to see if I have ADHD. I have some severe symptoms that point in that direction that have hurt our relationship. She says the she tried for months to see if her feelings would change and they haven't. But at the same time I hadn't really made any progress even though I had been trying. We also hadn't really gotten super deep into what the issues were and how to fix them. She would just get mad at me for things and I wouldn't understand what she was really needing. We've been on the verge of breaking up for around 2 or 3 weeks now and I explained to her that her feelings haven't changed because I hadn't changed. I explained that now that I understand the issues and changes needed, we can actually take the chance to see if the feelings rekindle with all of the changes having been made.

Is there anything else I could say or do to show that this isn't the time to throw in the towel?
