Look at the positives on his part as "baby steps". Celebrate them internally, but continue your DB'ing. If there's anything to take away from this it is that your DB'ing is WORKING, so don't stop now! A lot of people make the mistake of going into full-blown pursuit mode when their WAS starts showing interest, and that just drives the WAS away again. Be very patient, it is likely that he will start thinking things are "too good" and he'll push away again. Expect it and (hopefully) you won't be too upset when it happens.
