We have our first gottman based MC on Tuesday, looking forward to it.
If you've found a true Gottman based MC in your area, that really knows their sh1t, I'm a little jealous. A lot of MC spew around the basics of Gottman's research, but don't focus a practice around it. I hope to find someone like this in the future in my area, but then again, I'd just be happy if my W's corpse would be willing to consider going to MC at some point in the future again.
I'm assuming you've read the Gottman books? Our MC suggested both the "seven principles" and "five love languages" books to us on our first visit. My W said she read both, but when we discussed topics within them, I could tell she had no effing clue what was going on... Liar! haha.
I wish the best to you in your next MC session, Cnut.
