Can a loveless relationship last?

Yes, definitely, many can and do, but we need perhaps to take a big step back before judging this - love can take many forms.. in all likelihood there IS love, just not sexual love.. or romantic love..

I've communicated with many married men in my time.. most will say they love their wife and would never want to leave her... but they miss sex, want and desire sex and are miserable without it..sometimes they will call that love.. it's only one form of love.

Sure, people can make each other miserable until death if they want to. 🤷🏻‍♀️ It’s not recommended though.

Maybe but I couldn't be in a relationship without being loved.

They do.. unfortunately.

If they at least care about and have concern for each other, maybe yes

It can if there is an agreement in the marriage or relationship.
Many things are only arranged.

If she's rich. And has a cute butt.

Relationships are far more than just love.

it can...... but, i wouldnt suggest it.

Yes. The evidence is overwhelming

Well sure.

Yes.
