So my partner and I are 36, we have both been married twice before and neither of us wants to do it again. We have no children and don't want any, and we love each other very much. We have been together almost two years, we live together in a 200sqft tiny house in the woods, very dreamy.

Here's our issue: we both have insecure attachment styles and relationship anxiety. Trust issues. We are in therapy trying to work on it, but it feels we are getting further apart instead of closer. Our therapist told us last night he thinks neither one of us has really "jumped in" as far as commitment to the relationship and suggested we were both waiting for the other one to do it first. I don't think he's wrong.

We don't want to lose what we have. Are there any people here who have been successful at committing to a non traditional relationship who can share how they established said commitment w their partner?

Thanks in advance, A guy who loves his gf

EDIT: TL;DR: what are some things people who don't want to get married doing to demonstrate commitment to your relationship?
