You know what, I think that sentence says it perfectly :p an almost 'if i can't be with my kids, neither can you' version? So caught up in the personal emotion of the moment that rational thinking turns off and he can't see how his actions are bound to come between him and his kids eventually.
Oh you totally should, pfff safe, who wants that :p
In all honesty, that hadn't gone in properly - which I hasten to add isn't a reflection of your story telling (your spacing and timing at the end really does hinge the focus there really well) more my hectic life and very glad you highlighted that <3 It is a very unsettling notion, both how easy it to be the on coming headlights, the literal light at the end of someone else's dark tunnel. And how all it takes to escape is to stray over that little white strip of paint, (whilst fucking damn you! also forcing me to think about the other person on the other side of the road and consequences of a seemingly easy way out) it is a fitting way for the character to behave, once again so burdened by his emotion that the rational thinking ceases to function. It caps the story really well, bringing his behaviour full circle showing how, as much as the experience may have changed him, deep down when it comes to it, his emotions still take over.
And then the kicker of the note, cos regardless of what they found out, to have left them a note saying "I loved you more than anything in the world" - it blatantly isn't true, he hasn't actually put them or their feelings first. If he really did love them more than anything else in the world, he wouldn't have done either of those things. It feels more like he loved what he was to them, it was never a selfless love that wanted the best for them, and even a dad away in jail would have been better for the kids. Almost a fitting mirror of the original arrangement he could have had, weekend visitations and all. Must be a all or nothing sort of person. Although, the more I think about this, it kind of feels more like a story of a man crying out he has been blinded by love, when instead he can't see for the tears and the pain.
Overall, you have left me very glad I can't drive haha
