The first thing that jumps out at me is... how comfortable are you that the A is really over? It took my H several failed attempts to end it. Really, he never did. She did after I talked to her and set her straight about our M. Is there some level of transparency even now while he's out of the house? Maybe that's something that you can discuss with the FT.
Don't let it be all your fault. Keep calling him on his actions that got you here. Alot of them can really twist things back around so it gets to be your fault again.
You're handling this as well as any of us would want to. Good luck with the FT.
