There are a couple of schools of thought. Letting go/detaching is certainly important, but it doesn't mean you have to go NC. If you want, you can keep a log of what you are doing and see what works and what doesn't. You shouldn't bounce all over the place and you should give your chosen tack a while to see if it works. I am one of the believers of rebuilding the connection one month at a time by being positive and having little interactions like one-way texts and tag alongs with the kids. But nothing you do can seem needy or pressured.
