I think you should have let her in on the stark reality of not having you around at a time like this, there are going to be other times in life that she is going to need you, this is one of them. Sounds harsh, but you have to realize that this has been her decision.

Sorry for your loss, but I would definitely let her come to you, treat her as a friend by asking if there is anything that you could do for her and let her decide how much she needs you.
Be there for your kids, and yes Prozac helps

This would be a great time to "teach" her what life will be like without me, but I just can't do that to someone I care about. I know it's her choice, but the thought of her getting a call at 1:00am and then being alone until this morning, is just plain sad. I made the offer to have her spend the night(s) at our house and if she chooses to accept, she does. I suppose it's important that it not seem even remotely like I am using this an opportunity to earn brownie points.
As for the Prozac, I am feeling almost normal the last few days and I think it's likely due to it. I am concerned about becoming reliant on it, and getting off it, but that is an issue to deal with later.
