Well, there are too many quotes to put here, it would be a whole chapter, but let me give you some of my notes, with quotes interspersed. These are from Morgoth's Ring, and are accurate, I assure you. The page numbers are in parenthesis. (Hardback version)
These are from the section entitled: OF THE LAWS AND CUSTOMS AMONG THE ELDAR...

-Eldar married early, usually not long after age 50 (209)
-did not have many children: Fëanor held the record with seven. usually had four children or less (210)
-"Their families, or houses, were held together by love and a deep feeling for kinship in mind and body;...and the children needed little governing or teaching." (210)
-married only once, for love or by free will
-there are very few "deeds of lust among" the Eldar
-spirits of Eldar are in complete control of their bodies and "are seldom swayed by the desires of the body only, but are by nature continent and steadfast." (211)

TO MARRY
-may choose spouse early in life, even when they were still children (210)
-the parents of the children decide when they are to be married, unless the children were of an age to go ahead with marriage and wanted to be married very soon (210)
-when the engagement "was announced at a meeting of the two houses concerned" (210), the two to be married gave each other silver rings. the engagement lasted for a year or more. (210-211)
-at any time during the engagement the pair can call off the wedding by publicly returning the rings, which were then melted down so that they were never used again. breaking of engagement rare, vow to marry was never taken frivolously by the Eldar (211)
-after a year had passed, the engaged set the time for their wedding (211)
-at the time for the wedding, the houses of the two families got together for a feast to celebrate the marriage. (211)

"At the end of the feast the betrothed stood forth, and the mother of the bride and the father of the bridegroom joined the hands of the pair and bless them." (211)

"For this blessing there was a solemn form, but no mortal has heard it; though the Eldar say that Varda was named in witness by the mother and Manwë by the father; and moreover that the name of Eru was spoken (as was seldom done at any other time). (211)

-after the blessings were completed, the pair gave back the silver rings (to cherish forever) and exchanged gold rings that they wore on the right hand on the index finger. (211)
