About your house...maybe the fact that he's not been over there and done any DIY jobs on it could be reason enough that people aren't interested. A little paint, cleaning up the yard and ensuring that things are in their proper places goes a long way. Then again, it could be the area that the house is in and the asking price may be a bit steep, if it's not been kept up.
Or, he could be writing off some of the interest on his taxes. There could be any number of reasons the house hasn't sold. I wouldn't read too much into whether this is the end or not because the economy is slowly coming back up.
Well, as far as the account...he could very well sign both names or have his current wife sign for you, i.e., which is fraud and forgery. Where there's a will, there's a way and I'm sure he'll do something about it in short order if there is money in the account.
As for texting you by mistake...this happens even w/normal people, again, nothing to read into here.
I would just put all of this stuff on the back burner. It's nothing to sit around thinking about...except the sale of the vacant house.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
