Ok I am going to chime in because I have been there and I got schooled by 25years. Pink go read my post where 25years gave me the what for. It has worked.
Get out of his head, stop trying to second guess what he means, thinks, saying and doing. 25years said picture a big STOP sign when you start to do this or think anything about him and then stop.
Don't let him run your life day to day you need to stop. Who cares what he is doing about the D that is his problem just concentrate on what your attorney needs from you and if there is nothing then don't think about it, again STOP.
Only think about your children and you and when he comes over be cordial and then busy and don't but any thought into what he says, does or means.
Stop trying to fix him or care. If you have to text him about the house or you need him to fix something ask but do not apologize. If he fixes something thank him thank him thank him and then let it go.
It truly works 25years is so smart and I still will start to think oh what did that mean and then I see big red stop sign and say to myself who knows and who cares I must get on with it and then I find something to take my mind off of it.
Stop trying to find fault with what he did because it won't help, just let it go, he knows what he has done or will or maybe won't but who cares. Just fix what you need to for yourself.
