I remember it this way: "Inlove" can last a few days to 18 months, but up to many years when there are barriers to the relationship (thus 180, let them go, don't be a barrier)
And the dopamine high is replaced by an oxytocin/vasopressin "high" that fosters pair bonding, in a secure relationship. If the guy is a cad he'll go off to impregnate another but most likely will re-impregnate #1. Now I'm starting to confuse myself, I'd better stop!
