I am in a very similar sit as you, although my H didn't move out, but we are still in early stages of piecing, and I am very much like you, very scared that he will bolt! some days I can't think straight for worry.
All I can suggest is to ready the posts here, they do help alot! There is alot of good advice! check my link, and a long post from Cat, it was fantastic! Made be see things alittle differently in dealing with H.
Another thing I have been told time and time again is patience, patience,patience! and don't push!

Be calm(easier said then done)and be happy!
