I think the Buddha made pretty clear that the celibate life was far better for serious practice. For those unable to enter a celibate order, yes, one gets into householder arrangements of various sorts. They can be as virtuously navigated as possible.
Personal experience: When I practiced very seriously - I had no thoughts of 'being with' someone and wasn't pursuing, looking, sending out subconscious signals, getting imbalanced around people who flexed the metaphoric pair of biceps and said 'How intriguing you are" in some sort of mating game, etc. And my practice was going great, palpably wonderfully, actually
Then one day, Practical Thoughts overcame me and I thought thus: Since the monastic order is a bit of a mess worldwide, I was likely to end my days as a lay person. As a lay person, the world comprehends and embraces one better in a Pair. This also saves scarce fossil fuels, and provides the caring company that outside of Pairs, lay society does not much provide. So I decided to find me a mate. This required putting out signals "looking interested", being keenly attuned to the signals of anyone "interested in me", the awful fear of jealous angers in a world of singles all trying to hook up - and all of those things. My practice suffered - but of course! Of course it suffered!
And yes I'm 'in a relationship' now and my practice is not at all as sharp and committed as it used to be...how can it be, when no two people ever have the same pace or intensity of practice from moment to moment, yet everyday life is all synced up to be together every evening after work
The only tremendous relief is that my partner and I neither of us wants either kids or property
I still have thoughts of ordaining, which I've shared with him and mercifully, he does not judge
