I'm a terrible passenger, too! I mean THE WORST and mostly with H! It has been a big 180 for me to control that. I literally have to say to myself in my head, "in 18 years he hasn't killed me yet". I have to mentally zone out and music helps a lot in this department. This means that I basically have no idea where I am while in car with him because I'm purposely not paying attention. It has worked so far and he has totally noticed!
It's hard, huh?! Still, it's important.
Way to go. It's not easy to do these things that really jar the person we have been for so long.
Also, way to go on the invite to the park. Send it out and forget it. Him not accepting says nothing about you.
