I think if you are OK with the sex part, why not? My H had EA gone PA (I found out then), back to EA. I am still DBing and it is working. Part of it is the sex. For women, a hug and a kiss from h means he is showing affection. I think for men, the sex is part of us showing affection. I think it is up to you. It is just part of DB'ing. I sometimes try to detach and see doing it just for fun. At the lowest point of our M, when D was on my mind, I figured I probably won't have sex with anyone for a while, so I was actually more into it (last supper syndrome).
My h is also sitting on the fence now. He cannot decide. I am seeing him moving back to me so I don't want to push him just yet back to OW. I am letting OW do all that work :-) I am a happy person in front of him. At the same time, ONCE IN A WHILE, I do let him know that this A is still hurting me, and eventually I will give up, though I don't know when this may be. So H knows he cannot go on forever. But remember, that's his choice not to decide. It is your choice to wait or not. You will know when to keep DB'ing, and when to give up.
Not sure if this helps, but this is what I am doing.
