Yes, he is very petty and is acting like a two year old. If your grandfather made those things, then you should have them. They were a gift to you. I just get this impression that he is doing all of this BS to stall things and that he really doesn't want to go through w/a divorce.
I think they all get petty when it comes down to the home and what's in it. It's not about the fact that they really want the items, but the fact that they want control and for us to beg for things. My eh tried that, but he totally forgot who he was dealing with and my kindness and compassion were put on the back burner and the business side of me came out and he knew then, he wasn't going to have an easy time of it in negotiating w/me.
Know one is going to ask why you didn't get those things from the house because we all have made mistakes and many of us tend to think that maybe, just maybe these pod people will show a bit of compassion and give a little. We don't discover that they are complete and utter @sses until it comes down to splitting things up.
Now, you need to put your business suit on and look at this situation from the business side. You've been such a kind and compassionate woman thus far...but this deal sux and you need to toughen up. He wants a beanie, then he gives you the birdhouse. Time to play hard ball.
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.
