Mar brings her own catastrophizing to the relationship. I had a breakdown very early into my marriage that coincided with some negative, unforeseen side effects of prescription drugs, and that really fueled this bit. I became obsessed with death and disappearance into the ages, how little it all mattered. I needed the reassurance that life was happening RIGHT NOW, that it's something I was taking for granted (and taking things for granted is a blameless pleasure of youth), and that there's joy in appreciating the now and the continuity of life. It's wild to me now how hard I fought all this. Jane wants Mar to know how wonderful it is to submit to the uncertain and uncontrollable, that this love itself was something they couldn't have predicted, and that their life together is real, no matter how long it lasts.
