change your way of thinking about the things you already do
start to think of your daughter and you as a unit...he may come back later, he might not...you and your daughter are your unit NOW
so
instead of focusing thinking time wondering ifhe will notice this or call for that or how he like the sheets to smell or whatever....start putting the focus on you and your family unit
you like the smell of bounce but used whatever because he liked it change it to what you like
rediscover who you are
LSS left I had two smallish boys at home 3 jobs no freetime
but I still found time to wonder and hope and nag and cry and whatever
that time was much better spent when I started writing letters to friends, painting, reading books for my pleasure...not to figure out my love language or whatever (although those books are good)
