While a fade is often the easiest because it's gradual and 'under the radar', it has its' own inherant difficulties, namely
1. It takes months or years
2. You are never really free from future contact and efforts to bring you back.
An alternative which deals with both of these but requires dealing with conflict at the outset, is to come out and say that you do not wish to disassociate yourself, but you will not be going to meetings any more.
You will have to argue your point that not going to meetings is not synonymous with disassociation, but there are things you can say to remove the pressure a bit, like "I want to leave a way open for me in the future, but I can't do this right now". Don't get drawn in, don't accept a visit from two elders, just insist you have done nothing wrong but want to stop the meetings for now.
There will be efforts to help you, but deal with these and you can be free in a month.
Another option combines this break with a fade.
Start by fading and at the first attempt to 'help' you, instigate the break.
