It seems like you think that everyone's input in telling you to stay away from contacting her and this situation will make you a bad guy. The rest of us here are looking at your situation from an unbiased perspective as we are not attached to the situation. Although ultimately you will make the decision you should try to sit back and reflect on situations before you make a decision after you've calmed down your emotions which, clearly in this situation you haven't.
Sure ignoring your ex that you've only broken up with 2 weeks after her father died is a bit harsh but what good will come of it if you do console her. You think she will magically change and come back into your arms and you'll live happily ever after? Most likely she will appreciate your company for a few days and you'll be back to the same things that had you break-up in the first place. Now not only will she still feel horrible like another break-up just happened but her father is still dead. You will be no better. Both of you worse off than you would have been if you left it alone.
Now if you leave her alone you will feel like a heartless person and apparently you can't live it down. You don't have to completely ignore her.
Detach yourself from the situation, if you care about her and yourself you understand it's best you guys stay apart. Send her flowers and a card to her or her family that reminds her of happy times.
dozen white flowers and a card that says "Thank you HBx and mrs. xxx for having me over for all those wonderful dinners where I was able to enjoy the witty and hilarious company of Mr. XX. He was a great man and will be remembered as such."
Leave it at that. Show that you do care but are no longer in a situation that can warrant anything more a card and gift. If you do, you're not showing her or yourself the respect.
All in all, if you dwelve back into this, your only setting yourself up to be let down. Learn to control your emotions.
I would have probably just picked up a call once i found out about the death. Gave my condolences. Sent a card to the family with flowers and attended the funeral.

similiar to backbreaker, my oneitis called me back saying she thought she was pregnant, mom had cancer, she was going to commit suicide, etc. Every single time i went back to her only to have the crazy cycle repeat itself. Not everyone here is telling you to be an *******, we're just trying to teach you to learn how to control your emotions and protect yourself.
You can always exit like a respectful gentleman.
