There are detachment pros around here. I have been terrible at detaching but am getting better. Take baby steps. Try different things. Find what works. Here were my baby steps:
Spend more time physically apart (literally, give more space)
Find GAL activities where it is impossible to think (for me, this is the gym)
Do not initiate texts, calls, conversations, sex, anything
When falling asleep (my worst time for spinning), listen to music or a book
