Has anyone done marriage counselling?

Yes, we initially intended it to be more of a routine pre-marital counseling thing, not because anything was wrong.
Just bc we were engaged to be married.
Both his parents & my parents were supportive of this idea, too.

But life got busy.
And so we were slow to do so, and were already married almost 1 year by the time we got around to going a few times.

We looked at it like:

You do regular maintenance on your car or house upkeep, so why not invest in your marriage which is also important to continually work to keep strong?

We learned a little bit about the Gottman method philosophy from it, and a few techniques to help communication.

I liked going, but:
a) it got to be too expensive,
and
b) our counselor we liked left/changed employer, and at her new place they pressured clients to come in every 2 weeks, minimum. It was this new company's "rule" which we didn't like.
So we quit going, even though we liked the actual therapist.

We’ve tried 3 different marriage counselors/therapists.

I would say that for it to benefit, you have to find the right fit and both of you have to be willing to put the work in.

While my marriage is still struggling, the counseling has helped.

Marriage is tough and a lot of work 😅
