I’m 36 and have been with my current girlfriend for almost 5 years now - my longest relationship yet. We live together & everything else couply, just not married. I see marriage as unnecessary pressure that has a tendency to put strain on the relationship. Right now if we’re happy together we stay, if we’re not we split. Simple. Marriage complicates it.
For all intents and purposes you are married. Depending on where you live your relationship might even have a legal recognition despite not signing any papers.
Weddings are a waste of time and actually counterproductive to a stable relationship, I agree.
