<human>: A few weeks ago, my now ex ended our relationship on the grounds that she wasn't over her own ex.  Cool, I understand- shit happens.  No worries.

That being said, her dad still texts me from time to time wanting to talk and wanting to do stuff with me, e.g. target shoot, outdoorsy stuff, etc.  Truth be told, I don't think she's told her family that we're through.

I've not got an issue with hanging out with her dad, I actually like him a lot and consider him a good friend.  But I really don't want to antagonize my ex.  She wanted to remain friends and all, and I've not got a problem with that either.  Ithat being said, she's ignored my two texts that I sent a few weeks apart. I was just trying to establish some communication so that this kind of thing didn't wind up happening. 

I just really don't want to step on anyone's toes here.
I think it would be scummy of me not to at least make sure he knows about the whole situation.

Should I go ahead and give him the heads up and let him make his own decision?  Do I not tell him and hang out with him at the risk of antagonizing my ex?  What do?

Could you distill the essence of the text into 1-3 sentences?
<bot>: GF broke up with me, didn't tell her family.  Her dad still wants to hang out with me.  How do I handle this situation?
