She's so cute when she's sorry!
But according to a source close to the couple, the driving force behind their split might not be what you're thinking!
Apparently RiRi was sooo committed to their relationship, that she was already looking a few steps ahead and said she wouldn't mind settling down together in the future.
"She told him she loved him and could see herself starting a family with him in the future."
Not surprisingly, Breezy didn't respond well and said they were too young to be thinking about kids, which led to a big argument.
Things only got worse when he did a radio interview on the The Kyle & Jackie O show and said he couldn't "be focused on wife-ing someone that young!"
According to the source, that interview ended up being the straw that shattered the camel's back, and Rihanna decided it was time to move on with her life!
It's definitely sad to hear thing's had to end so poorly when RiRi was sooo committed, but it would have been even worse if things would have ended badly and there was a baby involved!
