I agree w/ Cutter- I know you guys live close by- stop the coffee and dinners, dont answer calls or texts- stop the hugs and asking to work on the marriage.
The GALing is the hardest part b/c mentally we are bogged down by things- like you said sitting on a time bomb. Fake it at first- go to a coffee house bring a lap top or book. Meet new people, etc. Hit the gym- see a movie go to the library- just stay busy and unseen.
