Well what I feel is friendship which will lead to good communication and constant communication means some deep secrete shared between lovers which boost trust which is a key factor to look forward to in a relationship, when trust is built love naturally happens which spice up the relationship but it's not complete without understanding, when there's understanding, couples feels secured, I must say money have a major role to play in a relationship no matter how small, let your lover see you put effort to getting him or her something on special days and invents in your lives, I guess this would cover for material things to spicing relationships (money) your boy @jstringz dropping this one right from my couch
