Yes @lucymae88 as you said, since we don't know the real truth we only have facts, and the facts speak by themselves, they don't want to be involved with Beljaflas.
Refering to your question about her behavior, I'm confused too since Mohammed and Roza are only two years apart each one, so practically when little Mohammed had 1 year Latifa got pregnant of Roza, that absolutely say that she had not a steady relationship with Rashid or maybe she's not the mother, considering she does not have baby or toddler photos of him.
*Note: The only picture of him as a toddler I have found is this one, and apparently it was taken as a screenshot from someone that is friends with Al Maktoum girls and then spread over the IG
