"She is insecure about their whole *thing*" Ma fahmin,maxaa ka wadhaa>??
Forget his qabiil,that shouldn't be an issue,if her parents have that qabiil mentality,ilaahi ha u naxariisto real talks.
"He has history with other girls" I'd be worrying about this part. Hadhii gabar fiicaan tahay oo waxbarashada iyo diinta ku xiran oo masaakiin ah,nin kale oo ayada la mid ah ha raadsato,not ninkaan oo suuqsa so marey.
In conclusion I'd say bun this guy.
That's my advice
