Helen Fisher, a Cultural Anthropologist has a lot to say about this.
See the website and her YouTube (Why we love, why we cheat) for a more exhaustive discussion:
1 Negotiator- Estrogen and oxytocin, attracted to builder, oxytocin-and vasopressin equal attachment that is secure and so you tolerate and stick with them long enough to raise kid
2 Builder- Serotonin, attracted to builder, loyal, formal- norepinephrine and lower levels of serotonine means romantic attraction can happen- triggers falling in love
3 Director Dopamine-attracted to negotiator, no emotion
4 Explorer- Testosterone- attracted to other explorers, curious, novelty- testosterone is good for sex drive- novelty and romance increase dopamine
