Dear Topsie:
Here in the US, Romany people marry fairly young compaired to the Gyzhen, but not illegaly young. Part of the reason is there a strong tradition against pre-marital sex. The marrages are arrainged by the families, yet the community is close, so the partners are not strangers, and can say yes or no.
As with the Gyzhen, there is a general acceptance of divorce and either the man or woman can move for divorce. However, there is a general tradition if there is a divorce to marry again, and second marrages have a bigger rate of permanence. Part is that there is a great sense of importance given to family.
All the best
Lorcan
