As someone native to the aforesaid "part of the world", I'll answer as I think it is meant between your context and hers:

For Ainaserkewen, a "fling of one's boyfriend" would be a short relationship had with another woman at a time other than that during which he was her boyfriend. Contextually, I would say before he was her boyfriend.

The English interpretation of the statement is that WHILE he was her boyfriend, he was off having a fling with another woman.

Have I got that right, or am I barking up the wrong tree, and everyone really means by fling "the action of throwing or the object thrown," in which case it might be appropriate for me to make a joke to the effect of "nobody flings a Dwarf!"
