Dear @nomad-magus ... I read this entire post,
what I understand is Crystal has one bf and than they leave each other and Crystal meet other guy in these months... so so so
My suggestion for Crystal is- to be confident on your love and analyse who give you more respect than other and also see who is your real care taker. Who can put himself in danger for you... because marriage is not one day business it is the Iife time engagement.
another thing that you discussed is that one person not to be limited for only their spouse. In our society we have act on this no one is permitted to love, sex or even meet for that purpose to any one. Our religion and norms bound us for that.
