Thanks for clarifying. I think you should take him at his word that he had the taxes withheld and paid the penalty. A "life policy" is generic, but it could have been an annuity or something through a workplace plan, which a 5% penalty sounds about right.
I think that the fact you don't have a desire to talk to him shows that you're detaching effectively.
As for asking for money- are you paying any of his bills while you two are apart? If you're sharing some of his expenses I wouldn't think it weird to ask for $300. If you're each self-sufficient at this point it might make less sense.
