God it is so hard when they start kicking us while we are down. I am quickly learning WSs do not take the low road, they take a tunnel!
I have a bit of a different perspective on this than Thornton but I cannot say mine is right or just the same as my grim mood. With that disclaimer, here it goes...
First, how much do you need the money? Say if your portion would be $300 is it something that would not make or break you? I know you are preparing for a move soon. Is that money something that if you did not have would ruin the move for you or would it just "come in handy." If it is something you definitely need or may hamper your career path, then I would say close the account or withdraw it all. I also agree with Broke, you need to check to see if it is still in there.
Second, the games you bought together. This is a little more tricky. Obviously, this was a ploy to get at you. Do you call him out on it or just let it be? You do not just want to be his door mat but you also do not want to give him validation why he is leaving. The other side of this is if he does not hear from you about this are you so GALing you don't even have time to play games anymore. What would he think about that??? So really I cannot say what to do in this circumstance. I guess it depends how important the games are to you? I guess this is a personal choice. If you do decide to call him out on the games, I would have already cleaned out the account.
The above is just MHO and not really based on what DR or DB says.
