Dont let yourself be the brundt of abuse.I know you believe that fiance is bp however that doesnt give him a right to emotionally control and abuse you.
If you just moved and your fiance is bp then the stress of relocating and the rest probably has got him into a hypomanic state which includes irritability.I know for me its very important to keep my enviroment very stable.Stability can be as small as a tidy,neat space or as big as avoiding triggers.
Sounds to me that you somehow need to intervene and get the help he needs.Its a tough one.
Good luck,I hope it works out.
