FWIW, I was divorced and alone at 41 and doing fine. Some lonely moments, but those beat the horrible stretches of bad relationships.
And my best friend was mid-40s after two failed marriages and also doing fine with the single thing, thank you very much.
So yes, staying single beats getting into a marriage just for the sake of marriage, by several orders of magnitude. Especially if (as in your case) you know what you want in a relationship.
