An exclusive relationship in the modern Muslim context usually involves one of two scenarios:
For second and third-generation Muslim girls in Western countries, love is also a geography problem. Is he "from back home" (traditional, familiar, but possibly controlling)? Or is he the convert at the MSA (understanding of her culture, but maybe not her family's specific quirks)? Or the non-Muslim (requiring a conversion or a massive family confrontation)? The exclusive relationship becomes a negotiation of identity, language, and belonging.
