That is a very odd question lol Also I'm pretty sure Blake Lively cheated on him with Ryan Reynolds (Reynolds himself told about it in some interview).
But ok let's dive in.
I'm not particular into marriage or kids nor do I think humans are biologically made for living in monogamous relationships. So in that instance Leo would be the perfect match for me 😄
But honestly I'm not made for his lifestyle nor am I his type (yeah I also think physically attraction is important). All the traveling, the partying, the constant sorround of young people I get exhausted just by observing it. His energy with almost 50 is admirable though. I hope he won't get a heartattack one day.
But I think he's gettin checked from time to time for prevention lol
