I am of the opinion that the 180 is not for everyone's and often is over recommended on here without knowing the details of each person's situation.
Why are you doing the 180?
I read a little bit of your story from other posts and you sound like you are very new since dday. If your WH expresses remorse (only time will tell if the remorse if real though), has cut off contact with AP, wants to continue M and is attempting to answer questions I dont think the full 180 is always a good idea. If you want more questions to be answered, keep asking them. Get the information you need.
It is perfectly ok to be in more of a not R and not D type mode so early - you don't need to do the full 180 to be in that mode. There are parts of the 180 that may be good for you - go ahead and do those things. It is important to be watching your WH actions right now as well as his words, he is going to have to earn back your trust. I recommend giving him plenty of opportunities to keep proving to you that he is capable of trust. Him answering your questions to help you test if you are getting truthful information is one of the ways to do this. If you do a full 180 you are not as able to test him.
Now if your WH was not giving remorse or not in no contact with AP or not wanting to continue M or not answering questions in your opinion then yes, 180 may be the route to go. The not remembering answer to some questions may be difficult to decide. Does your WH have a good memory typically? Is the question you asked something that might be hard to remember because it is very detailed? Sometimes it does take a WS a little while to stop and put together the details you want. Having them put together a written timeline may help. You will have to judge if the "I don't remember" answer is because he really doesn't remember or if it is he doesn't want to tell you.
