I DO feel that Dobson and Exposure are compatible. Having said that, I also think others have made "Letting Go" an approach that is different than Exposure. Dobson laid out no clear approach, just philosophies and protecting the line of respect. He left specifics (approach) to the individual to seek personal counseling on.
I'm saying this to not confuse anyone by my earlier statements, because anyone having read my posts knows I LOVE Dobson. I still feel that if you are seeking counsel (as Dobson advises) that you have to determine in each individual sitch as to the best specific course of action. Allen and Puppy are right on - Exposure and "Letting Go" are different forks that MAY lead to the same road...and you can go down both if the other one isn't working. However, I would listen to them about which to take first.
Each case is different and you have to go with what you feel is best in your case. Having said that, DO NOT let fear be your determining factor here. You can't take the letting go fork because you're too afraid of the other one! If you do so, take it because you have truly thought out why the other is better. Personally, it sounds to me you've already started down the Exposure road, so why back out of it now???
I'm not an expert in these specifics... I'll leave that to others. Just my 2cents.
