They are very cool. I put "?" after the BF part, because it just sounds weird, being at their age and whatnot. But I don't know what else to call it.
But his kids are cool too. We give each other presents on Bdays and at Christmas. And last year I held christmas with all of them plus my dad, which was great too. I would hate nothing more then to have divorced parents who couldn't stand each others company or even speak together. Luckily that isn't the case for my parents.
