You are in a very similar (gee, you think) situation as I was in about a month ago. Things SEEM great but then the damn OP comes into the picture again and destroys all that "greatness" going on around you. I say that IF you were never flat out told that the A was over (BTW, doesn't he deny it still?) then all that happened was that you THOUGHT it was over and thus, you are reacting now to your idea being proven wrong, or so you think, by this money being taken out, etc.
I think you just need to look at your goals, look inside to see what strength you have left, and then start to figure out what to do. I AM sensitive to what you are going through but I also know that you have been doing this for too long to give up now.
I think this is one of those times when only YOU can make this decision because there are circumstances that only you fully know. I trust you will do the right thing.
