Kirk / Picard / Christopher
It should be a large part of your concern. He is very intelligent, but intelligence doesn't automatically translate to maturity or experience. When you're young, you throw yourself into everything, thinking it'll work out or it's worth the potential pain because it's what you want. We're all short sighted when we're young and think we know exactly what we want or what's right for us. But I think you and I both know that as we get older, we start to get more grounded and look for different qualities. When I was younger, I would have never considered being life-bonded to a Vulcan.
Only you know what is right in this situation, but I think you asked for advice because you needed to hear what you already knew from someone else.
